IS 11169 (Part 1) 40Ni14 vs BS 970 (Part 3) 635M15

Related Material — 69.9% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 40Ni14 (IS 11169 (Part 1):1984) and BS 970 (Part 3) 635M15 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 40Ni14 is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1), while BS 970 (Part 3) 635M15 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) 40Ni14 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 635M15 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 40Ni14 vs BS 970 (Part 3) 635M15 is a 69.9% 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 69.9%.
