BS 970 (Part 3) 416S29 vs IS 1570 (Part 7) 20Cr12MoNiVH
Related Material — 64.7% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 416S29 (BS 970 (Part 3):1991) and IS 1570 (Part 7) 20Cr12MoNiVH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 416S29 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; martensitic stainless steel (table 17), while IS 1570 (Part 7) 20Cr12MoNiVH 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 3) 416S29 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 7) 20Cr12MoNiVH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 3) 416S29 vs IS 1570 (Part 7) 20Cr12MoNiVH is a 64.7% 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 64.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
