BS 970 (Part 1) 655M13 vs IS 11169 (Part 1) 13Ni14Cr3
Close Alternative — 81.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 655M13 (BS 970 (Part 1):1991) and IS 11169 (Part 1) 13Ni14Cr3 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 655M13 is typically used for case hardened gears, heavily loaded shafts, while IS 11169 (Part 1) 13Ni14Cr3 is commonly 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).
BS 970 (Part 1) 655M13 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 13Ni14Cr3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 655M13 vs IS 11169 (Part 1) 13Ni14Cr3 is a 81.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 81.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
