Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 316S11 (BS 970 (Part 1):1983) and ASTM A959 .- (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 316S11 is typically used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition)., while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
BS 970 (Part 1) 316S11 is defined under British Standards (BS), originating from United Kingdom, while ASTM A959 .- is defined under ASTM International, originating from United States.
As per chemical composition, BS 970 (Part 1) 316S11 vs ASTM A959 .- is a 65.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Typical Applications
BS 970 (Part 1) 316S11
Austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (Table 14, with Table 15 for the cold drawn condition).
ASTM A959 .-
Wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1)
Key Differences
BS 970 (Part 1) 316S11 specifies Mo which is not specified for ASTM A959 .-.
ASTM A959 .- specifies Cb, N, Ti which are not specified for BS 970 (Part 1) 316S11.
Can BS 970 (Part 1) 316S11 Be Substituted With ASTM A959 .-?
BS 970 (Part 1) 316S11 and ASTM A959 .- share some compositional similarity but differ enough that substitution should not be assumed. Review the differences above carefully, and consult the applicable standard or a metallurgist before using one in place of the other.
