Strong Match — 85.3% match
based on chemical composition and mechanical property overlap.
EN ISO 683-17 100Cr6 (EN ISO 683-17:2014) and IS 1570 (Part 6) T105Cr5 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 683-17 100Cr6 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 6) T105Cr5 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN ISO 683-17 100Cr6 vs IS 1570 (Part 6) T105Cr5 is a 85.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 85.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
