IS 11169 (Part 1) 15C8 vs IS 1570 (Part 2/Sec 1) 15C8

Strong Match — 100% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 15C8 (IS 11169 (Part 1):1984) and IS 1570 (Part 2/Sec 1) 15C8 (IS 1570 (Part 2/Sec 1):1979) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 15C8 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 IS 1570 (Part 2/Sec 1) 15C8 is commonly used for boiler billets, bars and sections, welded round link chains, billets and bars for forgings, carbon steel forgings and case hardened parts (the standard links this grade to is 2100, is 6967, is 1875, is 2004, is 4432). IS 11169 (Part 1) 15C8 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 2/Sec 1) 15C8 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, IS 11169 (Part 1) 15C8 vs IS 1570 (Part 2/Sec 1) 15C8 is a 100% 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 100%.
