BS 970 (Part 1) 416S41 vs IS 1570 (Part 7) 12Cr12MoVH
Close Alternative — 76.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 416S41 (BS 970 (Part 1):1983) and IS 1570 (Part 7) 12Cr12MoVH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 416S41 is typically used for stainless and heat resisting steel for mechanical and allied engineering purposes (table 13)., while IS 1570 (Part 7) 12Cr12MoVH is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
BS 970 (Part 1) 416S41 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 7) 12Cr12MoVH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 416S41 vs IS 1570 (Part 7) 12Cr12MoVH is a 76.4% 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 76.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
