EN ISO 4957 1.2316 vs IS 1570 (Part 7) 3Cr17Ni12Mo3H
Related Material — 65% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 1.2316 (EN ISO 4957:2018) and IS 1570 (Part 7) 3Cr17Ni12Mo3H (IS 1570 (Part 7):1992) are both steel grades.
EN ISO 4957 1.2316 is classified under Tool & Die Steels, while IS 1570 (Part 7) 3Cr17Ni12Mo3H is classified under Stainless Steel — a different category, which is worth noting alongside the chemistry match below.
EN ISO 4957 1.2316 is typically used for plastic injection moulds for corrosive materials, food packaging moulds, while IS 1570 (Part 7) 3Cr17Ni12Mo3H is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
EN ISO 4957 1.2316 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 7) 3Cr17Ni12Mo3H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN ISO 4957 1.2316 vs IS 1570 (Part 7) 3Cr17Ni12Mo3H is a 66.4% 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 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
