IS 11169 (Part 2) X04Cr17 vs IS 1570 (Part 7) 12Cr12MoH
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 2) X04Cr17 (IS 11169 (Part 2):2023) and IS 1570 (Part 7) 12Cr12MoH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
IS 11169 (Part 2) X04Cr17 is typically used for cold heading and cold extrusion of stainless steel parts; the standard covers wires, wire rods and bars of 0.8 to 25 mm (clause 1.1, table 13), while IS 1570 (Part 7) 12Cr12MoH is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
IS 11169 (Part 2) X04Cr17 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 7) 12Cr12MoH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 11169 (Part 2) X04Cr17 vs IS 1570 (Part 7) 12Cr12MoH is a 62.2% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
