IS 1570 (Part 7) 12C7H vs IS 11169 (Part 1) 14C6

Close Alternative — 75.2% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 12C7H (IS 1570 (Part 7):1992) and IS 11169 (Part 1) 14C6 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 7) 12C7H is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while IS 11169 (Part 1) 14C6 is commonly used for cold heading and cold extrusion of parts not heat treated after cold forming; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex a). IS 1570 (Part 7) 12C7H is defined under Bureau of Indian Standards (IS), originating from India, while IS 11169 (Part 1) 14C6 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, IS 1570 (Part 7) 12C7H vs IS 11169 (Part 1) 14C6 is a 75.2% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 75.2%.
