Strong Match — 88.3% match
based on chemical composition and mechanical property overlap.
EN 10084 16NiCrS4 (EN 10084:2008) and IS 1570 (Part 4) 16Ni4Cr3 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 16NiCrS4 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 4) 16Ni4Cr3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 16NiCrS4 vs IS 1570 (Part 4) 16Ni4Cr3 is a 88.3% 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 88.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
