Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 S21800 (ASTM A959:2011) and IS 6911 X07Cr17 (IS 6911:1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 S21800 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 6911 X07Cr17 is commonly used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1).
ASTM A959 S21800 is defined under ASTM International, originating from United States, while IS 6911 X07Cr17 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 S21800 vs IS 6911 X07Cr17 is a 72.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
