SAE 1141 Resulfurized Steel Bars

Short Answer for SAE 1141 Steel Bar Buyers

Junxiong Metal can review and supply buyer-specified SAE 1141 resulfurized carbon steel bar enquiries in round, flat, square, hexagonal and drawing-based sections. Buyers should state the exact governing standard and edition, 1141 grade designation, product route, dimensions, tolerance, delivery condition, machining process, downstream forming or joining, required properties, quantity, destination and heat-specific MTC scope.

SAE 1141 is a distinct SAE grade route. It is not an automatic substitute for SAE 1117, SAE 1144, SAE 1215 or SAE 12L14. Similar machining use or a shared grade-family number does not approve substitution; the purchase specification and matching batch records control acceptance.

Representative Junxiong Steel Bar Shapes

Representative Junxiong cold drawn round steel bars with circular cross sections — Representative round-bar form. This image does not identify an SAE 1141 heat or batch.

Representative Junxiong cold drawn flat steel bars in multiple widths — Representative flat-bar form. Grade, machining condition and dimensional conformity require the approved order and batch records.

Representative Junxiong cold drawn square steel bars with square cross sections — Representative square-bar form. Appearance cannot establish chemistry, delivery condition or heat identity.

Representative Junxiong cold drawn hexagonal steel bars with six-sided cross sections — Representative hexagonal-bar form. Quote and acceptance remain subject to the exact SAE 1141 standard route and MTC.

Image boundary: these owner-supplied Junxiong photographs show relevant bar shapes only. They are not SAE 1141 grade, stock, shipment or batch evidence.

Supply Scope and Evidence Boundary

Junxiong has confirmed commercial supply capability for buyer-specified SAE 1141 resulfurized steel bar requirements. Factory feasibility is reviewed for the exact standard, product route, shape, size, delivery condition, machining process, downstream operations, required properties, quantity and destination.

Evidence boundary: this page does not publish a matching SAE 1141 shipment, current-stock record or heat-specific MTC. Supply capability and representative photographs do not prove conformity of a future order. Batch acceptance requires the approved purchase specification, heat identity, matching MTC and agreed inspection results.

SAE 1141, 1117, 1144, 1215 and 12L14 Are Separate Decisions

Buyer search route	Correct sourcing treatment	Required control
SAE 1141 steel	Use the buyer-specified SAE route and the ordered bar-product specification.	Exact standard, shape, dimensions, delivery condition, machining route, downstream operations, properties and MTC.
SAE 1117 steel	Separate lower-carbon free-cutting grade route.	Do not infer interchangeability from the shared 11xx family or machining use.
SAE 1144 / Stressproof®	SAE 1144 is a separate grade; Stressproof® is a trademarked processed product.	Do not use 1144 or the Stressproof® name as an alias for SAE 1141.
SAE 1215 / 12L14	Separate free-cutting grades with different purchase and restricted-substance decisions.	Confirm exact chemistry standard, lead/restricted-substance requirements, shape, size, condition and MTC.
Regional comparison grades	Search or inquiry terms only until the buyer identifies the governing document.	Written buyer approval is required before any cross-standard substitution.

Technical Facts Buyers Must Confirm

Decision	RFQ information required
Grade route	SAE 1141 with the governing SAE, ASTM or buyer-approved specification and required edition.
Product route	Cold drawn, bright drawn, turned/peeled, ground, hot wrought or another specified route. Grade chemistry does not define the finished bar.
Delivery condition	State as-drawn, stress relieved, annealed or another agreed condition, including hardness or mechanical-property requirements where applicable.
Dimensions	Shape, diameter or full section, tolerance, straightness, twist or flatness, corner/edge form, length and machining allowance.
Machining route	State machine type, bar feeder, cutting operation, surface/straightness needs and whether trial machining is required.
Downstream process	State forming, heading, welding, plating, heat treatment or another operation so feasibility and qualification requirements can be reviewed.
Restricted substances	State contractual, destination-market and end-customer limits, especially when comparing any leaded or free-machining alternative.
Traceability	Specify heat identity, MTC fields, product analysis, mechanical testing and any third-party inspection.
Commercial data	Quantity per size, trial and annual demand, packing, destination country, port and delivery schedule.

1141 Round Bar, Flat Bar, Square Bar, Hex Bar and Custom Sections

Shape	Buyer must state	Factory review
1141 round bar	Diameter, tolerance, straightness, surface, bar-feeder length, condition and machining route.	Starting material, reduction route, condition, inspection, MOQ and schedule for the exact grade-size combination.
1141 flat bar	Width, thickness, edge condition, flatness, straightness, surface and length.	Feasibility depends on starting section, reduction, tooling, surface controls, condition and quantity.
1141 square bar	Side size, tolerance, corner radius, twist, straightness, condition and length.	Feasibility depends on starting section, reduction, tooling, surface controls and quantity.
1141 hex bar	Across-flats size, tolerance, corner form, twist, straightness, condition and bar-feeder length.	Feasibility depends on starting section, reduction, tooling, surface controls and quantity.
1141 custom profile	Dimensioned drawing, datums, critical tolerances, radii, condition, annual demand and trial quantity.	Drawing review covers material flow, tooling, first-article inspection, machining datums and downstream use.

Typical Buyer Applications

Buyer-specified round or hexagonal feedstock for CNC and bar-fed machining.
Machined blanks where the buyer controls final design, properties and component validation.
Flat, square and drawing-based sections used as near-net machining stock after feasibility review.
SAE research examples include drive-shaft yokes and connecting rods; those studies do not approve another component, condition or batch.

Application suitability depends on the exact standard, section size, delivery condition, machining route, downstream forming or joining, restricted-substance requirements and finished-component validation. The buyer remains responsible for final grade and process approval.

Buyer Checklist Before Quotation

SAE 1141 designation, governing standard and standard edition.
Product route, shape, finished dimensions and machining allowance.
Dimensional tolerance, straightness, twist, flatness, corner/edge and length limits.
Delivery condition, hardness or mechanical-property requirements.
Machine type, bar feeder, machining operation, surface and trial requirements.
Downstream forming, heading, welding, plating or heat-treatment route.
Restricted-substance, MTC, heat-traceability and inspection requirements.
Quantity per size, annual demand, destination, schedule and packing.

FAQ for SAE 1141 Steel Bar Buyers

Is SAE 1141 a resulfurized machining-steel route?

SAE J403 is the current SAE chemistry route, and SAE Technical Paper 890513 discusses resulfurized steel bars in an SAE 1141 machining study. The purchase order must still state the exact governing specification, product route, shape, condition and required testing.

Is SAE 1117 the same as SAE 1141?

No. They are separate SAE grade routes. A shared 11xx family and machining use do not approve substitution.

Can 1144, 1215 or 12L14 replace 1141?

Not automatically. They are separate grade routes. Similar machining use does not approve substitution, and generic 1144 must not be represented as a trademarked Stressproof® product.

Can Junxiong review round, flat, square and hexagonal 1141 bars?

Yes. Junxiong can review these shapes and drawing-based sections after confirming the exact standard, dimensions, condition, machining route, tooling, quantity and destination.

Can a representative photograph prove SAE 1141?

No. Bar shape and appearance cannot establish grade, heat identity or delivery condition. The approved purchase specification and matching heat-specific documents are required.

What information is needed for a useful factory quotation?

Send the exact grade and standard, product route, shape, dimensions, tolerance, condition, machining process, downstream operations, restricted-substance limits, inspection scope, quantity and destination.
