Close Alternative — 80.2% match
based on chemical composition and mechanical property overlap.
IS 6911 X15Cr16Ni2 (IS 6911:1992) and ASTM A959 630 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X15Cr16Ni2 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while ASTM A959 630 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6911 X15Cr16Ni2 is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 630 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6911 X15Cr16Ni2 vs ASTM A959 630 is a 80.2% 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 80.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
