BS 970 EN353 vs IS 11169 (Part 1) 15Ni5Cr4Mo1

Strong Match — 87.6% match based on chemical composition and mechanical property overlap.

BS 970 EN353 (BS 970:1955) and IS 11169 (Part 1) 15Ni5Cr4Mo1 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Alloy Steel category. BS 970 EN353 is typically used for heavily loaded gears, cams, camshafts, while IS 11169 (Part 1) 15Ni5Cr4Mo1 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 EN353 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 15Ni5Cr4Mo1 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 EN353 vs IS 11169 (Part 1) 15Ni5Cr4Mo1 is a 87.6% 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 87.6%.
