Strong Match — 90.5% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 30Cr4Mo2 (IS 1570 (Part 4):1988) and DIN 17200 30CrMo4 (DIN 17200:1986) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 30Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while DIN 17200 30CrMo4 is defined under Deutsches Institut fur Normung (DIN), originating from Germany.
As per chemical composition, IS 1570 (Part 4) 30Cr4Mo2 vs DIN 17200 30CrMo4 is a 90.5% 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 90.5%.
