IS 1570 (Part 7) 12Cr12MoVH vs ASTM A959 201L

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 12Cr12MoVH (IS 1570 (Part 7):1992) and ASTM A959 201L (ASTM A959:2011) are both steel grades. Both fall under the Stainless Steel category. IS 1570 (Part 7) 12Cr12MoVH is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while ASTM A959 201L is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). IS 1570 (Part 7) 12Cr12MoVH is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 201L is defined under ASTM International, originating from United States.

As per chemical composition, IS 1570 (Part 7) 12Cr12MoVH vs ASTM A959 201L is a 48.2% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
