Strong Match — 87.7% match
based on chemical composition and mechanical property overlap.
IS 4367 15Cr3 (IS 4367:1991) and IS 11169 (Part 1) 15Cr3 (IS 11169 (Part 1):1984) 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 11169 (Part 1) 15Cr3 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1).
IS 4367 15Cr3 is defined under Bureau of Indian Standards (IS), originating from India, while IS 11169 (Part 1) 15Cr3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 4367 15Cr3 vs IS 11169 (Part 1) 15Cr3 is a 98.3% match.
As per mechanical properties, the match is 66.7%.
Combined, this makes them a strong match overall at 87.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
