Close Alternative — 70.4% match
based on chemical composition and mechanical property overlap.
IS 6911 X04Cr17Ni12Mo2 (IS 6911:1992) and ASTM A959 16-8-2H (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X04Cr17Ni12Mo2 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while ASTM A959 16-8-2H is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6911 X04Cr17Ni12Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 16-8-2H is defined under ASTM International, originating from United States.
As per chemical composition, IS 6911 X04Cr17Ni12Mo2 vs ASTM A959 16-8-2H is a 70.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 70.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
