BS 970 (Part 1) 635H15 vs IS 11169 (Part 1) 12Ni3Cr2

Related Material — 69.4% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 635H15 (BS 970 (Part 1):1991) and IS 11169 (Part 1) 12Ni3Cr2 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Alloy Steel category. BS 970 (Part 1) 635H15 is typically used for case hardening steel (section four), while IS 11169 (Part 1) 12Ni3Cr2 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) 635H15 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 12Ni3Cr2 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 (Part 1) 635H15 vs IS 11169 (Part 1) 12Ni3Cr2 is a 69.4% 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 69.4%.
