Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
SAE J404 4140 (SAE J404:2009) and IS 4367 07Cr4Mo6 (IS 4367:1991) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4140 is defined under SAE International, originating from United States, while IS 4367 07Cr4Mo6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, SAE J404 4140 vs IS 4367 07Cr4Mo6 is a 63.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
