Strong Match — 92.2% match
based on chemical composition and mechanical property overlap.
ASTM A959 201 (ASTM A959:2011) and IS 6911 X10Cr17Mn6Ni4N20 (IS 6911:1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 201 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 6911 X10Cr17Mn6Ni4N20 is commonly used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1).
ASTM A959 201 is defined under ASTM International, originating from United States, while IS 6911 X10Cr17Mn6Ni4N20 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 201 vs IS 6911 X10Cr17Mn6Ni4N20 is a 92.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 92.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
