Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4804 SUM22 (JIS G 4804:2021) and IS 1570 (Part 3) 10C8S10 (IS 1570 (Part 3):1979) are both steel grades.
Both fall under the Free Machining Steel category.
JIS G4804 SUM22 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 1570 (Part 3) 10C8S10 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4804 SUM22 vs IS 1570 (Part 3) 10C8S10 is a 75.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
