Strong Match — 94.5% match
based on chemical composition and mechanical property overlap.
EN 10084 16MnCrB5 (EN 10084:2008) and IS 4367 16Mn5Cr4 (IS 4367:1991) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 16MnCrB5 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while IS 4367 16Mn5Cr4 is commonly used for manganese-chromium case-hardening steel; used for gears, shafts, and transmission components requiring good core strength and hardenability.
EN 10084 16MnCrB5 is defined under European Standard (EN), originating from Europe, while IS 4367 16Mn5Cr4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 16MnCrB5 vs IS 4367 16Mn5Cr4 is a 91.8% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 94.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
