Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 431S29 (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) 431S29 is typically used for ferritic and martensitic 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) 431S29 is defined under British Standards (BS) (United Kingdom).
As per chemical composition, BS 970 (Part 1) 431S29 vs GOST 5632 08X18H10 is a 64.9% 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.
