Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 304S31 (BS 970 (Part 1):1991) and GOST 5632 08X18H10 (GOST 5632-2014) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 304S31 is typically used for austenitic stainless and heat resisting steel (section five), while GOST 5632 08X18H10 is commonly used for chemical equipment, food processing, general corrosion resistant applications.
BS 970 (Part 1) 304S31 is defined under British Standards (BS) (United Kingdom).
As per chemical composition, BS 970 (Part 1) 304S31 vs GOST 5632 08X18H10 is a 82.8% match.
As per mechanical properties, the match is 33.3%.
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.
