Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
DIN 17210 15CrMo5 (DIN 17210:1986) and IS 1570 (Part 4) 103Cr6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17210 15CrMo5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while IS 1570 (Part 4) 103Cr6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, DIN 17210 15CrMo5 vs IS 1570 (Part 4) 103Cr6 is a 65.7% 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.
