Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 6911 X40Cr13 (IS 6911:1992) and IS 1570 (Part 7) 7Cr18Ni10H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X40Cr13 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while IS 1570 (Part 7) 7Cr18Ni10H is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
IS 6911 X40Cr13 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 7) 7Cr18Ni10H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 6911 X40Cr13 vs IS 1570 (Part 7) 7Cr18Ni10H is a 70.5% 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.
