IS 6911 X04Cr18Ni10Nb vs ASTM A959 347

Strong Match — 100% match based on chemical composition and mechanical property overlap.

IS 6911 X04Cr18Ni10Nb (IS 6911:1992) and ASTM A959 347 (ASTM A959:2011) are both steel grades. Both fall under the Stainless Steel category. IS 6911 X04Cr18Ni10Nb is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while ASTM A959 347 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). IS 6911 X04Cr18Ni10Nb is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 347 is defined under ASTM International, originating from United States.

As per chemical composition, IS 6911 X04Cr18Ni10Nb vs ASTM A959 347 is a 100% 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 100%.
