Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 41Cr3 (IS 11169 (Part 1):2022) and JIS G4103 SNCM439 (JIS G4103:1979) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 41Cr3 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while JIS G4103 SNCM439 is commonly used for crankshafts, gears, heavy duty shafts, aircraft components.
IS 11169 (Part 1) 41Cr3 is defined under Bureau of Indian Standards (IS), originating from India, while JIS G4103 SNCM439 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, IS 11169 (Part 1) 41Cr3 vs JIS G4103 SNCM439 is a 70.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
