Close Alternative — 83.7% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 7) 7Cr19Ni11TiH (IS 1570 (Part 7):1992) and ASTM A959 348H (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 1570 (Part 7) 7Cr19Ni11TiH is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while ASTM A959 348H is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 1570 (Part 7) 7Cr19Ni11TiH is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 348H is defined under ASTM International, originating from United States.
As per chemical composition, IS 1570 (Part 7) 7Cr19Ni11TiH vs ASTM A959 348H is a 83.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 83.7%.
