Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 90MnCrV8 (EN ISO 4957:2018) and IS 1570 (Part 6) 133T3 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 4957 90MnCrV8 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 6) 133T3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN ISO 4957 90MnCrV8 vs IS 1570 (Part 6) 133T3 is a 57.3% 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.
