Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
JIS G4104 SCr415 (JIS G 4104:1979) and IS 1570 (Part 4) 105Cr5 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
JIS G4104 SCr415 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 1570 (Part 4) 105Cr5 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4104 SCr415 vs IS 1570 (Part 4) 105Cr5 is a 80.7% 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.
