Strong Match — 86% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 15Cr6Ni6 (IS 1570 (Part 4):1988) and EN 10084 17CrNi6-6 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 15Cr6Ni6 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 17CrNi6-6 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 1570 (Part 4) 15Cr6Ni6 vs EN 10084 17CrNi6-6 is a 86% 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 86%.
Frequently Compared With IS 1570 (Part 4) 15Cr6Ni6:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
