Related Material — 67.7% match
based on chemical composition and mechanical property overlap.
ASTM A959 348 (ASTM A959:2011) and IS 1570 (Part 7) 12Cr13H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 348 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 1570 (Part 7) 12Cr13H is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
ASTM A959 348 is defined under ASTM International, originating from United States, while IS 1570 (Part 7) 12Cr13H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 348 vs IS 1570 (Part 7) 12Cr13H is a 67.7% 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 67.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
