Strong Match — 96.7% match
based on chemical composition and mechanical property overlap.
ASTM A959 SS310 (ASTM A959:2011) and BS 970 (Part 1) 310S31 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 SS310 is typically used for furnace parts, heat exchangers, kiln components, while BS 970 (Part 1) 310S31 is commonly used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition)..
ASTM A959 SS310 is defined under ASTM International, originating from United States, while BS 970 (Part 1) 310S31 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, ASTM A959 SS310 vs BS 970 (Part 1) 310S31 is a 96.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 96.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
