IS 11169 (Part 1) 16Ni3Cr2 vs BS 970 (Part 1) 635M15

Strong Match — 85% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 16Ni3Cr2 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 635M15 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 16Ni3Cr2 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 1) 635M15 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties).. IS 11169 (Part 1) 16Ni3Cr2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 635M15 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 16Ni3Cr2 vs BS 970 (Part 1) 635M15 is a 85% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 85%.
