Related Material — 64.9% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 1.2316 (EN ISO 4957:2018) and IS 6603 X03Cr17Ni12Mo3 (IS 6603:2024) are both steel grades.
EN ISO 4957 1.2316 is classified under Tool & Die Steels, while IS 6603 X03Cr17Ni12Mo3 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 6603 X03Cr17Ni12Mo3 is commonly used for general purposes, semi-finished products, bars, wire rods and bright bars.
EN ISO 4957 1.2316 is defined under European Standard (EN), originating from Europe, while IS 6603 X03Cr17Ni12Mo3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN ISO 4957 1.2316 vs IS 6603 X03Cr17Ni12Mo3 is a 64.9% 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 64.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
