EN 10088-3 X90CrMoV18 vs IS 1570 (Part 7) 12Cr12MoH
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10088-3 X90CrMoV18 (EN 10088-3:2014) and IS 1570 (Part 7) 12Cr12MoH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-3 X90CrMoV18 is typically used for general purposes, semi-finished products, bars, rods, wire, sections and bright products, while IS 1570 (Part 7) 12Cr12MoH 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 X90CrMoV18 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 7) 12Cr12MoH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-3 X90CrMoV18 vs IS 1570 (Part 7) 12Cr12MoH is a 56.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
