Close Alternative — 84% match
based on chemical composition and mechanical property overlap.
ASTM A959 XM-15 (S30310) (ASTM A959:2011) and IS 6911 X07Cr18Ni9 (IS 6911:1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 XM-15 (S30310) is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 6911 X07Cr18Ni9 is commonly used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1).
ASTM A959 XM-15 (S30310) is defined under ASTM International, originating from United States, while IS 6911 X07Cr18Ni9 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 XM-15 (S30310) vs IS 6911 X07Cr18Ni9 is a 84% 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 84%.
