Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10088-3 X3CrNb17 (EN 10088-3:2014) and IS 1570 (Part 7) 12Cr13H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-3 X3CrNb17 is typically used for general purposes, semi-finished products, bars, rods, wire, sections and bright products, 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.
EN 10088-3 X3CrNb17 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 7) 12Cr13H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-3 X3CrNb17 vs IS 1570 (Part 7) 12Cr13H is a 70.1% match.
As per mechanical properties, the match is 53.3%.
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.
