IS 11169 (Part 1) 35Ni5Cr2 vs BS 970 (Part 1) 637H17
Close Alternative — 71.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 35Ni5Cr2 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 637H17 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 35Ni5Cr2 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while BS 970 (Part 1) 637H17 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10)..
IS 11169 (Part 1) 35Ni5Cr2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 637H17 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 35Ni5Cr2 vs BS 970 (Part 1) 637H17 is a 71.9% 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 71.9%.
Frequently Compared With IS 11169 (Part 1) 35Ni5Cr2:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
