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

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

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

As per chemical composition, ASTM A959 619 vs IS 1570 (Part 7) 25Cr2MoVH 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%.
