IS 11169 (Part 1) 20Ni7Mo2 vs IS 1570 (Part 7) 10Cr36Mo10H
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20Ni7Mo2 (IS 11169 (Part 1):2022) and IS 1570 (Part 7) 10Cr36Mo10H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 20Ni7Mo2 is typically used for cold heading and cold extrusion of parts that are case hardened; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex b), 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 11169 (Part 1) 20Ni7Mo2 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 11169 (Part 1) 20Ni7Mo2 vs IS 1570 (Part 7) 10Cr36Mo10H is a 54.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Frequently Compared With IS 11169 (Part 1) 20Ni7Mo2:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
