Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S30909 (ASTM A240/A240M:2025) and GOST 5632 08X18H10 (GOST 5632-2014) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S30909 is typically used for pressure vessels and general applications (plate, sheet and strip), while GOST 5632 08X18H10 is commonly used for chemical equipment, food processing, general corrosion resistant applications.
ASTM A240/A240M S30909 is defined under ASTM International (United States).
As per chemical composition, ASTM A240/A240M S30909 vs GOST 5632 08X18H10 is a 63.8% match.
As per mechanical properties, the match is 66.7%.
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.
