316Ti Stainless Steel Equivalents | 1.4571 Cross-Reference

ASTM A240 / ASME SA240 Type 316Ti (UNS S31635) 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.

This page is a standalone technical article. For the primary overview on the original URL, see ASTM A240 / ASME SA240 Type 316Ti primary specification page.

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
ASME	SA240 Type 316Ti	ASME twin
EN	1.4571 / X6CrNiMoTi17-12-2	Common European counterpart - confirm edition
ASTM	Type 316L / 321	Different C/stabilizer strategy
UNS	S31635	316Ti designation

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 (ASTM A240 / ASME SA240 Type 316Ti)

Ti stabilization binds carbon/nitrogen; confirm Ti vs 5x(C+N) on the MTC.

Element	Min %	Max % / requirement
C	-	<=0.08
Mn	-	<=2.00
Si	-	<=0.75
P	-	<=0.045
S	-	<=0.030
Cr	16.0	18.0
Ni	10.0	14.0
Mo	2.00	3.00
N	-	<=0.10
Ti	5x(C+N)	0.70

Mechanical Properties (ASTM A240 / ASME SA240 Type 316Ti)

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

Property	Requirement
Tensile strength, min	515 MPa (75 ksi)
Yield strength (0.2% offset), min	205 MPa (30 ksi)
Elongation in 50 mm, min	40%
Hardness, max	217 HBW / 95 HRB
Delivery condition	Solution annealed

Frequently Asked Questions

What are the common equivalents for ASTM A240 / ASME SA240 Type 316Ti?

Buyers typically cross-reference ASTM A240 / ASME SA240 Type 316Ti with the related designations listed in the map above. Related grades in the same family are not automatic substitutes. Primary overview: ASTM A240 / ASME SA240 Type 316Ti.

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 ASTM A240 / ASME SA240 Type 316Ti?

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 ASTM A240 / ASME SA240 Type 316Ti 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 ASTM A240 / ASME SA240 Type 316Ti when equivalents are also named?

State ASTM A240 / ASME SA240 Type 316Ti (UNS S31635) 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 ASTM A240 / ASME SA240 Type 316Ti (UNS S31635), dimensions, quantity, delivery condition, optional NDT/PMI, and certificate (EN 10204 3.1 standard; 3.2 when third-party inspection is ordered). Gangsteel supplies export plate and related products with mill test certificates. Contact Gangsteel for stock and mill production RFQs.
