IS 11169 (Part 1) 27C15 vs JIS G4053 SMn438

Strong Match — 88.9% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 27C15 (IS 11169 (Part 1):1984) and JIS G4053 SMn438 (JIS G4053:2008) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 27C15 is typically 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, while JIS G4053 SMn438 is commonly used for agricultural equipment, heavy duty shafts. IS 11169 (Part 1) 27C15 is defined under Bureau of Indian Standards (IS), originating from India, while JIS G4053 SMn438 is defined under Japanese Industrial Standards (JIS), originating from Japan.

As per chemical composition, IS 11169 (Part 1) 27C15 vs JIS G4053 SMn438 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%.
