Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 6911 X20Cr25Ni20 (IS 6911:1992) and GOST 5632 08X18H10 (GOST 5632-2014) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X20Cr25Ni20 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while GOST 5632 08X18H10 is commonly used for chemical equipment, food processing, general corrosion resistant applications.
IS 6911 X20Cr25Ni20 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 6911 X20Cr25Ni20 vs GOST 5632 08X18H10 is a 64.4% 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.
