IS 11169 (Part 1) 10Ni5Cr4 vs BS 970 (Part 3) 637M17
Related Material — 68.7% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 10Ni5Cr4 (IS 11169 (Part 1):2022) and BS 970 (Part 3) 637M17 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 10Ni5Cr4 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 BS 970 (Part 3) 637M17 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy case hardening steel (table 15).
IS 11169 (Part 1) 10Ni5Cr4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 637M17 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 10Ni5Cr4 vs BS 970 (Part 3) 637M17 is a 68.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 68.7%.
