Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 4367 15Cr3 (IS 4367:1991) and IS 1570 (Part 7) 10Cr36Mo10H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Alloy Steel category.
IS 4367 15Cr3 is typically used for low-alloy chromium case-hardening steel; used for gears, shafts, and transmission components requiring higher core strength and wear resistance than plain carbon case-hardening grades, while IS 1570 (Part 7) 10Cr36Mo10H is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
IS 4367 15Cr3 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 7) 10Cr36Mo10H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 4367 15Cr3 vs IS 1570 (Part 7) 10Cr36Mo10H is a 68% 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.
