Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS316L (JIS G4304:2021) and IS 1570 (Part 7) 12Cr12MoH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS316L is typically used for hot-rolled stainless steel plates and strips, while IS 1570 (Part 7) 12Cr12MoH is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
JIS G4304 SUS316L is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 1570 (Part 7) 12Cr12MoH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4304 SUS316L vs IS 1570 (Part 7) 12Cr12MoH is a 59.9% 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.
