Close Alternative — 81% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 15Cr6Ni6 (IS 1570 (Part 4):1988) and JIS G4102 SNC415 (JIS G 4102:1979) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 15Cr6Ni6 is defined under Bureau of Indian Standards (IS), originating from India, while JIS G4102 SNC415 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, IS 1570 (Part 4) 15Cr6Ni6 vs JIS G4102 SNC415 is a 81% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 81%.
