Strong Match — 98.3% match
based on chemical composition and mechanical property overlap.
IS 5517 42Cr4Mo2 (IS 5517:1993) and IS 1570 (Part 4) 42Cr4Mo2 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
IS 5517 42Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 4) 42Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 5517 42Cr4Mo2 vs IS 1570 (Part 4) 42Cr4Mo2 is a 98.3% 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 98.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
