IS 6603 X110Cr17 vs IS 1570 (Part 7) 11Cr17Ni13W3TiH
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 6603 X110Cr17 (IS 6603:2024) and IS 1570 (Part 7) 11Cr17Ni13W3TiH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X110Cr17 is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while IS 1570 (Part 7) 11Cr17Ni13W3TiH is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
IS 6603 X110Cr17 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 7) 11Cr17Ni13W3TiH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 6603 X110Cr17 vs IS 1570 (Part 7) 11Cr17Ni13W3TiH is a 60.9% 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.
