BS 970 (Part 1) 316S13 vs IS 1570 (Part 7) 12Cr13H
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 316S13 (BS 970 (Part 1):1991) and IS 1570 (Part 7) 12Cr13H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 316S13 is typically used for austenitic stainless and heat resisting steel (section five), while IS 1570 (Part 7) 12Cr13H 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) 316S13 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 7) 12Cr13H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 316S13 vs IS 1570 (Part 7) 12Cr13H is a 63.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
