BS 970 (Part 1) 635H15 vs IS 11169 (Part 1) 16Ni3Cr2

Strong Match — 85.9% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 635H15 (BS 970 (Part 1):1983) and IS 11169 (Part 1) 16Ni3Cr2 (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Alloy Steel category. BS 970 (Part 1) 635H15 is typically used for case hardening steel supplied to specified hardenability limits (end quench test, table 10)., while IS 11169 (Part 1) 16Ni3Cr2 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1). BS 970 (Part 1) 635H15 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 16Ni3Cr2 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) 16Ni3Cr2 is a 85.9% 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 85.9%.
