ASTM A959 304LN vs IS 1570 (Part 7) 11Cr17Ni13W3TiH
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
ASTM A959 304LN (ASTM A959:2011) and IS 1570 (Part 7) 11Cr17Ni13W3TiH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 304LN is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), 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.
ASTM A959 304LN is defined under ASTM International, originating from United States, while IS 1570 (Part 7) 11Cr17Ni13W3TiH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 304LN vs IS 1570 (Part 7) 11Cr17Ni13W3TiH is a 55.6% 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.
