ASTM A513 Type 5
ASTM A513 Type 5 DOM Tube Supplier
For an A513 Type 5 order, confirm three identities before comparing prices: Type 5 DOM, the steel grade and the thermal condition. Then identify which OD, ID and wall limits control the component. This creates a reviewable purchase requirement instead of treating “DOM” as a complete material designation.
Type 5 is a manufacturing type within A513, not a chemical grade. The registered page remains in the grades directory for discovery, while the technical content keeps type and grade separate.
Type identity
Make the Type 5 order unambiguous
Type 5 names a manufacturing route inside A513. It sits in the same callout as the steel grade and the thermal condition, and each of the three is a separate requirement that has to be resolved before offers can be compared.
| Decision | Why it matters here | Before you enquire |
|---|---|---|
| A drawing explicitly calls for Type 5 | The exact type belongs on the quotation and certificate review. | Reject a silent change to another A513 type. |
| The drawing says only “DOM” | Grade and thermal condition still need resolution. | Ask the design authority to complete the material callout. |
| The drawing says seamless | A Type 5 welded product is outside that route requirement. | Obtain approval before considering a different specification. |
Explore the full steel-tubes range to compare the seamless, welded, ERW, mechanical and precision routes on one page before the drawing is fixed.
Review the wider DOM buying decision
Resolve whether DOM is appropriate before locking the specific A513 order.
Navigate ASTM product and grade requirements
Avoid transferring a material callout from another product form without review.
Enquiry builder
ASTM A513 Type 5 DOM Tube Specification — enquiry builder
Capture the decisions below, prepare a review summary and copy it to the tube RFQ. Check that the offer explicitly states Type 5, steel grade and thermal condition. Have the mill resolve simultaneous dimensional limits and supplementary testing before order acceptance.
Acceptance basis
Put the acceptance basis on the order
Type 5 is a manufacturing type within A513, not a chemical grade. The registered page remains in the grades directory for discovery, while the technical content keeps type and grade separate.
| Specification decision | Applicability and limit | Evidence to request | RFQ action |
|---|---|---|---|
| Type designation | The type describes the manufacturing route. | Offer and mill documentation explicitly identifying Type 5. | Keep Type 5 outside the chemistry field. |
| Grade and condition | One type does not fix all material properties. | Ordered grade, treatment and applicable test evidence. | State grade, condition and required properties. |
| Dimensional basis | A part can depend on bore, OD or wall in different ways. | Agreed limits for the ordered type and size. | Mark controlling dimensions and measurement method. |
| Supplementary requirements | Optional requirements need explicit agreement. | Accepted order schedule and inspection plan. | List additional tests and acceptance owner. |
No tolerance value, chemistry limit or mechanical-property requirement is published on this page. Every figure used in a live enquiry must come from the ASTM A513/A513M edition the contract invokes or from your own drawing.
Documentation
Documents that support an A513 Type 5 DOM tube order
Review the offer for silent type or condition changes before production. At release, compare the actual heat record, type identity and agreed dimensional report with the purchase order rather than relying on the DOM label.
| Control | What to examine | When and limits | Next action |
|---|---|---|---|
| Type designation | Offer and mill documentation explicitly identifying Type 5. | Before material acceptance; confirm feasibility and cost at quotation. | Keep Type 5 outside the chemistry field. |
| Grade and condition | Ordered grade, treatment and applicable test evidence. | Before material acceptance; confirm feasibility and cost at quotation. | State grade, condition and required properties. |
| Dimensional basis | Agreed limits for the ordered type and size. | Before material acceptance; confirm feasibility and cost at quotation. | Mark controlling dimensions and measurement method. |
| Heat and item identity | Mill test certificate linked to heat markings and packing list. | Before release and again on receipt; a sample certificate is not evidence for the shipped heat. | Request traceability through cutting, bundling and delivery. |
Duty and drawing
Follow the operating duty to the right specification
The drawing and service envelope govern acceptance. These paths address different purchasing decisions; an application label does not approve a material.
Automotive part specifications
Tie Type 5 acceptance to the approved part drawing and validation plan.
Machined sleeves and spacers
Review usable machining allowance and the specified material condition.
Manufacturing supply schedules
Keep repeat orders aligned to the same type, grade and revision.
GCC markets
Plan the GCC destination around the Type 5 supply
Use the destination to close the quotation scope, then confirm feasibility and commercial terms in writing. Country flags identify the destination; quotation must confirm the supply route, origin and availability for this order.
Show Type 5, chemistry grade and condition separately on destination item records. Identify the emirate, fabricator or site address and unloading restrictions; distinguish a domestic handover from an import leg.
Show Type 5, chemistry grade and condition separately on destination item records. Name the consignee, importer and final site; ask who confirms product classification and border documentation before dispatch.
Show Type 5, chemistry grade and condition separately on destination item records. State the nominated receiving point and project document approver; align certificate review with the required arrival window.
Show Type 5, chemistry grade and condition separately on destination item records. Specify the actual port, border point or inland site requested; separate the entry leg from onward transport and unloading.
Show Type 5, chemistry grade and condition separately on destination item records. Identify the contractor or fabrication yard receiving the tubes; agree import-document responsibility and the named delivery place.
Show Type 5, chemistry grade and condition separately on destination item records. Confirm whether the order is for local consumption or onward shipment; name the consignee and agree who handles each transport leg.
Commercial
Compare offers on the same delivered scope
Request a line-by-line exception schedule for type, grade, condition, cut length and inspection. Compare rejected-length allowance and minimum order basis as well as price; apparent dimensional similarity does not make a different type equivalent.
Ask for the offered mill and origin, tube schedule, quantity basis, processing scope, packing, commercial validity and exclusions. State the Incoterm with its named place and edition, who unloads, and the requested delivery window. Price, availability, production allocation, transport feasibility and dates require written confirmation — this page does not publish a price, and every figure remains price on request.
Coordinate an export enquiry — align tube identification, bundle protection and transport documents with the named delivery place before dispatch.
Adjacent decisions
Resolve the remaining specification decisions
Use these checks to finish the Type 5 callout before requesting competing offers.
Resolve OD, ID and wall limits
Identify the ordered dimensional basis rather than inferring guaranteed bore from nominal arithmetic.
Agree the Type 5 surface scope
State whether the delivered drawn surface is sufficient or further finishing is required.
Expert insight
Expert Insight: Why must Type 5 and grade be separate?
ASTM lists type and grade as different specification dimensions. A Type 5 callout therefore leaves chemistry unresolved.
Buyer implication: give the purchaser separate fields for type, grade and condition.
Method: review of the publisher’s classification and order-scope description. Applicability: A513 type/grade distinction. Limit: does not reproduce detailed acceptance clauses or certify an offered heat.

Acceptance controls
Make acceptance easier to demonstrate
Three controls carry most of the acceptance risk on a Type 5 order. Each one is settled before the purchase order, not at the machining centre.
Type designation
Offer and mill documentation explicitly identifying Type 5.
Keep Type 5 outside the chemistry field.
Grade and condition
Ordered grade, treatment and applicable test evidence.
State grade, condition and required properties.
Dimensional basis
Agreed limits for the ordered type and size.
Mark controlling dimensions and measurement method.
From specification to receipt
Close each decision before releasing the order
A Type 5 order passes four gates. Each one has an owner, a required input and an output that can be checked — and each one can fail silently if it is left open.
| Stage and owner | Required input | Evidence or output | Risk and next action |
|---|---|---|---|
| Engineering release — Buyer’s design authority | Approve a complete Type 5, grade and thermal-condition callout. | Approved specification and drawing revision | Unapproved substitution can change the design basis. Close the item before proceeding. |
| Offer review — Buyer and quotation team | Resolve mill exceptions against the controlling dimensional schedule. | Written technical exceptions and commercial scope | An unlisted exception can survive into the purchase order. Close the item before proceeding. |
| Material release — Mill, inspector and buyer as agreed | Accept heat-linked tests and the agreed Type 5 documentation. | Accepted documents linked to the order items | Missing heat identity can make an otherwise correct tube unacceptable. Close the item before proceeding. |
| Receipt and reconciliation — Receiving team | Reconcile cut lengths and item markings before production use. | Delivery record, item count and discrepancy record | Record any mismatch before the material is incorporated into work. Close the item before proceeding. |
FAQ
Questions before you place the tube order
Short answers to the points that most often delay a Type 5 enquiry.
Is Type 5 a steel grade?
No. It identifies the DOM manufacturing type. A steel grade and thermal condition are separate requirements.
Can another A513 type be offered?
It may be quoted as an explicit exception, but the design authority must approve it before purchase.
Does this route move if Type 5 is not a grade?
The registered URL stays unchanged. The content and enquiry fields correctly distinguish the manufacturing type from chemistry.
Can OD and wall arithmetic guarantee ID?
No. Actual bore depends on the accepted dimensional limits and measurements. State the controlling dimensions.
Must supplementary tests be requested?
Any requirements beyond the agreed base specification need explicit order agreement, including method, sampling and acceptance.
Is a Type 5 certificate enough for the finished part?
It supports incoming material acceptance. Finished-part dimensions, fatigue, welding or pressure qualification require the applicable separate approvals.
