IS 11169 (Part 1) 21Ni2Cr2Mo2 vs IS 4367 20NiCrMo2
Strong Match — 95.4% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 21Ni2Cr2Mo2 (IS 11169 (Part 1):2022) and IS 4367 20NiCrMo2 (IS 4367:1991) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 21Ni2Cr2Mo2 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 4367 20NiCrMo2 is commonly used for nickel-chromium-molybdenum case-hardening steel; used for highly stressed gears, shafts, and transmission components requiring high core strength, toughness, and wear-resistant carburized surface.
IS 11169 (Part 1) 21Ni2Cr2Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while IS 4367 20NiCrMo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 11169 (Part 1) 21Ni2Cr2Mo2 vs IS 4367 20NiCrMo2 is a 95.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 95.4%.
