Strong Match — 88.9% match
based on chemical composition and mechanical property overlap.
JIS G4053 SMn438 (JIS G4053:2008) and IS 11169 (Part 1) 27C15 (IS 11169 (Part 1):1984) are both steel grades.
Both fall under the Carbon Steel category.
JIS G4053 SMn438 is typically used for agricultural equipment, heavy duty shafts, while IS 11169 (Part 1) 27C15 is commonly used for manganese case-hardening steel; used for gears, shafts, and machine components requiring case hardening where higher core strength than plain carbon grades is needed.
JIS G4053 SMn438 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 11169 (Part 1) 27C15 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4053 SMn438 vs IS 11169 (Part 1) 27C15 is a 88.9% 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 88.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
