Strong Match — 86.9% match
based on chemical composition and mechanical property overlap.
JIS G4404 SKD61 (JIS G4404:2006) and IS 1570 (Part 6) XT35Cr5MoV1 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
JIS G4404 SKD61 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 1570 (Part 6) XT35Cr5MoV1 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4404 SKD61 vs IS 1570 (Part 6) XT35Cr5MoV1 is a 86.9% 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 86.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
