Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 6911 X04Cr18Ni10Nb (IS 6911:1992) and GOST 5632 12Kh13 (GOST 5632-2014) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X04Cr18Ni10Nb is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while GOST 5632 12Kh13 is commonly used for turbine blades, pump shafts, fasteners, cutlery.
IS 6911 X04Cr18Ni10Nb is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 6911 X04Cr18Ni10Nb vs GOST 5632 12Kh13 is a 62.9% match.
As per mechanical properties, the match is 0%.
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.
