IS 1570 (Part 7) 25Cr2MoVH vs ASTM A959 619

Related Material — 64.9% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 25Cr2MoVH (IS 1570 (Part 7):1992) and ASTM A959 619 (ASTM A959:2011) are both steel grades. IS 1570 (Part 7) 25Cr2MoVH is classified under Alloy Steel, while ASTM A959 619 is classified under Stainless Steel — a different category, which is worth noting alongside the chemistry match below. IS 1570 (Part 7) 25Cr2MoVH 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 619 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). IS 1570 (Part 7) 25Cr2MoVH is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 619 is defined under ASTM International, originating from United States.

As per chemical composition, IS 1570 (Part 7) 25Cr2MoVH vs ASTM A959 619 is a 64.9% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 64.9%.
