Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GOST 4543 40HNM (GOST 4543-2016) and IS 1570 (Part 7) 10Cr36Mo10H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Alloy Steel category.
GOST 4543 40HNM is typically used for used for crankshafts, gears, axles, heavy shafts, and machine tool parts., 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 1570 (Part 7) 10Cr36Mo10H is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, GOST 4543 40HNM vs IS 1570 (Part 7) 10Cr36Mo10H is a 53.7% 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.
