Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 6) 70T3 (IS 1570 (Part 6):1996) and DIN EN ISO 4957 1.2379 (DIN EN ISO 4957:2018-11) are both steel grades.
Both fall under the Tool & Die Steels category.
IS 1570 (Part 6) 70T3 is defined under Bureau of Indian Standards (IS), originating from India, while DIN EN ISO 4957 1.2379 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 1570 (Part 6) 70T3 vs DIN EN ISO 4957 1.2379 is a 54.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
