SAE 1144 Cold Drawn Hexagonal and Round Steel Bars

Short Answer for SAE 1144 Steel Bar Buyers

Junxiong Metal can supply and review SAE 1144 cold drawn steel bar enquiries, with historical quotation evidence for hexagonal bars and factory review available for round bars. Buyers should state the governing SAE or ASTM route, shape, finished size, tolerance, straightness or twist limit, surface, delivery condition, length, quantity, destination and MTC requirements.

SAE 1144 is a resulfurized medium-carbon steel designation used in machining-related applications. It is not another name for 1215 or 12L14. It must also not be marketed as Stressproof® unless the supplied product is the genuine Niagara LaSalle processed and trademarked product.

Image boundary: steel grade cannot be verified from appearance. These owner-supplied Junxiong images show relevant hexagonal and round cold-drawn bar forms only; they are not grade, heat, chemistry, mechanical-property or shipment evidence.

Commercial Evidence and Its Limits

Junxiong’s private commercial archive contains a 2024 quotation for SAE 1144 hexagonal bar in 12.7 mm, 15.875 mm and 19.05 mm across-flats sizes. This supports prior capability to review and quote those SAE 1144 hex-bar requirements.

Evidence boundary: a quotation is not a production record, shipment record, heat certificate or finished-batch inspection report. It does not prove current stock, completed delivery, heat identity or conformity of another order. Current availability and compliance are confirmed only against the approved specification, factory review and order-specific batch documents.

SAE 1144 Hexagonal and Round Bar RFQ Fields

Shape Buyer must state Why it matters
Hexagonal bar Across-flats size, tolerance, twist, straightness, corner condition, length and end condition. Across-flats control and twist affect chucking, feeding and machined-part consistency.
Round bar Diameter, tolerance, straightness, surface, length and bar-feeder requirement. Diameter, surface and straightness affect automatic-lathe and CNC feeding.
Custom section Dimensioned drawing, datum scheme, critical tolerances, corner radii, trial quantity and annual demand. Drawing-based sections require tooling, reduction-route and inspection review before price confirmation.

Technical Facts Buyers Must Confirm

Decision Required RFQ information
Grade route SAE 1144 with the governing SAE, ASTM or buyer-approved specification and required edition.
Shape Hexagonal, round or a dimensioned custom section requiring engineering review.
Dimensions Across-flats size or diameter, tolerance, straightness or twist, corner condition, machining allowance and length tolerance.
Delivery condition Cold drawn or bright condition, plus any buyer-defined stress relief, hardness, strength or machining requirement.
Inspection Heat identity, MTC type, chemistry, mechanical properties, hardness and dimensional inspection requirements.
Application Finished component, machining route, bar-feeder requirement and any critical fatigue, strength or heat-treatment requirement.
Commercial data Quantity per size, repeat demand, packing, destination country, port and delivery schedule.

1.0762 / 44SMn28 Compared With SAE 1144 Steel Bar

Short answer: 1.0762 steel and 44SMn28 steel are a European material-number and grade-name route that appears in current Swiss Steel bright-steel data. Swiss Steel also states that the chemical analysis of its proprietary ETG® 88/100 product corresponds to SAE 1144 and 44SMn28 (1.0762). This producer statement is useful for RFQ comparison, but it does not make generic SAE 1144, 44SMn28 / 1.0762 and ETG® automatically interchangeable.

Buyer search or RFQ term What the public evidence supports What the purchase order must control
SAE 1144 steel bar A resulfurized medium-carbon SAE designation. Quote it to the named SAE / ASTM route and required delivery condition. Exact specification and edition, chemistry, cold-finished condition, shape, size, strength or hardness requirements, inspection and heat-specific MTC.
44SMn28 / 1.0762 steel Swiss Steel publicly identifies 44SMn28 with material number 1.0762 and lists a cold-drawn bright-steel route. Current applicable standard, exact grade designation, +C or other ordered condition, dimensions, mechanical requirements, quantity and MTC.
ETG® 88 or ETG® 100 A proprietary Swiss Steel product family with defined processing and properties. Its published analysis is described as corresponding to SAE 1144 and 44SMn28 (1.0762). Genuine branded-product origin and documentation. Do not replace the ETG® name with generic SAE 1144 or 1.0762 wording, or the reverse, without written approval.

RFQ route for 1.0762 and 44SMn28 buyers

  • State whether the order is for SAE 1144, 44SMn28 / 1.0762, genuine ETG®, or a buyer-approved comparison review.
  • Identify the governing standard and edition instead of relying only on an equivalence table or search result.
  • State round, hexagonal or drawing-based section, finished dimensions, tolerance, straightness or twist, surface, length and end condition.
  • Define the delivery condition and required strength, hardness, machinability or downstream heat-treatment route.
  • Require the order-specific MTC and any dimensional, surface or mechanical inspection report needed for acceptance.

Evidence boundary: the sources below describe standards and Swiss Steel products. They are not Junxiong heat certificates, stock records or proof that a future batch conforms. Final acceptance is based on the approved purchase specification and matching order-specific documents.

SAE 1144 Is Not Automatically Stressproof®

Searches for 1144 steel often include the term 1144 Stressproof, but the terms are not interchangeable. Niagara LaSalle states that Stressproof® is its trademarked product made through a defined cold-drawing and stress-relieving process. A generic SAE 1144 cold-drawn bar should not be described, certified or quoted as Stressproof® unless it is that genuine product and the documentation supports the claim.

Buyer wording Correct quotation route
SAE 1144 cold drawn bar Quote to the named SAE or ASTM route, dimensions, delivery condition and order-specific property requirements.
Stressproof® bar Confirm genuine Niagara LaSalle product, trademarked process route and supporting product documentation before quotation.
1144 with stress relief Define the required heat-treatment route, mechanical properties, hardness, straightness and inspection criteria; do not convert the phrase into a Stressproof® claim.

Standards and Primary Reference Sources

  • SAE J403_202402: the SAE publisher source for chemical compositions of SAE carbon steels. SAE notes that current grade designations are SAE designations because AISI no longer issues them.
  • ASTM A108-24: the active ASTM specification route for carbon and alloy cold-finished steel bars.
  • Niagara LaSalle Stressproof® facts: the trademark owner’s product and processing explanation used to prevent incorrect generic use of the Stressproof® name.

Reference boundary: publisher and trademark-owner pages support specification routing and terminology. They are not Junxiong MTCs and do not prove a particular heat, batch, property level or branded-product origin.

SAE 1144 Compared With 1215 and 12L14

Question Buyer guidance
Are they the same grade? No. SAE 1144, SAE 1215 and SAE 12L14 are separate designations and must not be merged into one chemistry or certificate claim.
Can they all appear in machining enquiries? Yes, but their chemistry, lead content, strength potential, heat-treatment route and component requirements differ.
Can one replace another? Only after the buyer or design authority approves the governing standard, chemistry, properties, process and final component requirements in writing.
What controls the quotation? The exact grade, finished section, tolerance, delivery condition, inspection requirement and order quantity.

Buyer Checklist Before Quotation

  • SAE 1144 and the governing specification and edition.
  • Hexagonal across-flats size, round diameter or dimensioned custom-section drawing.
  • Dimensional tolerance, twist or straightness, corner and surface requirements.
  • Cold-drawn, stress-relieved or other delivery condition, with required hardness and mechanical properties.
  • Random or fixed length, end condition, packing and bar-feeder requirements.
  • MTC, heat traceability and inspection requirements.
  • Finished component, machining route and any safety-critical requirements.
  • Quantity per size, repeat demand, destination and required schedule.

FAQ for SAE 1144 Steel Bar Buyers

Can Junxiong supply SAE 1144 hexagonal bar?

Yes, subject to factory review of the exact specification. Send the across-flats size, tolerance, twist, straightness, length, condition, quantity and destination. Historical quotation records support prior review of 12.7 mm, 15.875 mm and 19.05 mm across-flats sizes.

Can SAE 1144 round bar also be reviewed?

Yes. State the diameter, tolerance, straightness, surface, length, condition, quantity and bar-feeder requirement.

Is SAE 1144 the same as 1215 or 12L14?

No. They are separate grades. Junxiong does not substitute one for another without written buyer approval.

Is every SAE 1144 bar Stressproof®?

No. Stressproof® is a Niagara LaSalle trademarked and processed product. Generic SAE 1144 cold-drawn bar must not be represented as Stressproof® without genuine product documentation.

Can Junxiong provide an MTC?

MTC and heat-traceability requirements can be reviewed by order. State the certificate type and test items before production.

Should a buyer specify only hardness?

No. The order should also identify the governing grade specification, delivery condition, chemistry, section, dimensions and required mechanical properties.

Are 44SMn28 and 1.0762 the same RFQ designation?

Swiss Steel publicly identifies 44SMn28 with material number 1.0762. Buyers should still state the applicable standard, edition, delivery condition and acceptance requirements on the purchase order.

Can 1.0762 / 44SMn28 be ordered automatically as SAE 1144?

No. Swiss Steel states that the analysis of its proprietary ETG® 88/100 product corresponds to SAE 1144 and 44SMn28 (1.0762), but that producer comparison is not a universal substitution rule. The buyer must approve the exact standard, chemistry, delivery condition, properties and MTC route.
