AISI 1146 Equivalents & Cross-Reference

AISI/SAE 1146 (UNS G11460) resulfurized free-machining carbon steel is frequently cross-referenced to related ASTM/ASME, EN, and other designations. This equivalents page leads with that cross-reference map, then summarizes chemistry and mechanical limits used to judge dual marking. Near-equivalents are not automatic code substitutes.

Equivalents and Cross-Reference Map

Use the table for RFQ orientation and dual-cert discussions. True dual certification exists only when one heat meets every chemical and mechanical limit of each named specification on the same MTC. Class society, PED, or ASME dossier wording still controls acceptance.

System	Grade	Note
UNS	G11460	Unified number
Near	AISI 1144 / 1141 family	Other resulfurized free-machining grades

Substitution caveat: Do not swap grades based on marketing strength bands alone. Chemistry, heat treatment, impact temperature, and product form must be reviewed by the responsible engineer before any concession.

Chemical Composition - Base Grade (AISI/SAE 1146 resulfurized free-machining carbon steel)

Standard AISI 1146 heat analysis. Resulfurized free-machining grade - S is intentional.

Element / rule	Requirement
C	0.42-0.49
Mn	0.70-1.00
S	0.08-0.13
P, max	0.040

Mechanical Properties (AISI/SAE 1146 resulfurized free-machining carbon steel)

Confirm thickness, specimen orientation, and any supplementary impact, UT, or hardness requirements on the PO.

Property	Requirement
Hot-rolled tensile (typical)	~585 MPa
Hot-rolled yield (typical)	~325 MPa
Hot-rolled elongation (typical)	~18%
Hot-rolled hardness (typical)	~170 HB
Cold-drawn tensile/yield (typical)	~655 / ~565 MPa
Note	Final properties depend on temper/reduction - use MTC

Frequently Asked Questions

What are the common equivalents for AISI/SAE 1146 resulfurized free-machining carbon steel?

Buyers typically cross-reference AISI/SAE 1146 resulfurized free-machining carbon steel with the related designations listed in the map above. Related grades in the same family are not automatic substitutes.

Is a near-equivalent always acceptable on an ASME or PED dossier?

No. The material specification listed on the calculation sheet, PED appraisal, or purchaser material list controls acceptance. Certificate marks must match unless a formal concession is approved.

How should dual marking be requested for AISI/SAE 1146 resulfurized free-machining carbon steel?

List every required standard on the purchase order and ask the mill to print all approved designations on one MTC only when the heat qualifies against each. Gangsteel confirms which heats can honestly carry those marks before allocation.

What is a safe way to compare AISI/SAE 1146 resulfurized free-machining carbon steel with near-equivalents?

Compare chemistry ranges, tensile/yield windows, impact temperature if specified, delivery/heat-treatment practice, and product form side by side. Name-alike grades can still fail dossier acceptance.

Does a sibling class or grade count as an equivalent?

Sibling classes (for example Class 1 vs Class 2, or Grade A vs B) share a family but intentionally different strength or toughness tiers. Ordering the wrong tier undercuts the design assumption.

How do I RFQ AISI/SAE 1146 resulfurized free-machining carbon steel when equivalents are also named?

State AISI/SAE 1146 (UNS G11460) resulfurized free-machining carbon steel as the governing grade, then list any dual marks required. Include dimensions, quantity, delivery condition, optional tests, certificate type, destination, and which mark governs acceptance.

Ordering and Mill Certificates

State grade AISI/SAE 1146 (UNS G11460) resulfurized free-machining carbon steel, dimensions, quantity, delivery condition, optional NDT/PMI, and certificate (EN 10204 3.1 standard; 3.2 when third-party inspection is ordered).
