Related Material — 62.7% match
based on chemical composition and mechanical property overlap.
BS 970 EN55 (BS 970:1955) and IS 1570 (Part 7) 12Cr13H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN55 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars., 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 EN55 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 EN55 vs IS 1570 (Part 7) 12Cr13H is a 62.7% 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 62.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
