EN ISO 4957 X30WCrV9-3 vs IS 1570 (Part 6) XT33W9Cr3V4
Close Alternative — 83.5% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 X30WCrV9-3 (EN ISO 4957:2018) and IS 1570 (Part 6) XT33W9Cr3V4 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 4957 X30WCrV9-3 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 6) XT33W9Cr3V4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN ISO 4957 X30WCrV9-3 vs IS 1570 (Part 6) XT33W9Cr3V4 is a 83.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 83.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
