Strong Match — 89.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 316S33 (BS 970 (Part 1):1983) and ASTM A959 SS316 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 316S33 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 SS316 is commonly used for marine, chemical, pharmaceutical, food processing equipment.
BS 970 (Part 1) 316S33 is defined under British Standards (BS), originating from United Kingdom, while ASTM A959 SS316 is defined under ASTM International, originating from United States.
As per chemical composition, BS 970 (Part 1) 316S33 vs ASTM A959 SS316 is a 89.4% 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 89.4%.
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) 316S33
Austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (Table 14, with Table 15 for the cold drawn condition).
Can BS 970 (Part 1) 316S33 Be Substituted With ASTM A959 SS316?
BS 970 (Part 1) 316S33 and ASTM A959 SS316 overlap closely enough on chemistry and mechanical properties that ASTM A959 SS316 is often considered as a substitute for BS 970 (Part 1) 316S33 in many applications.
