Strong Match — 100% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 7) 6Cr17Ni12Mo2H (IS 1570 (Part 7):1992) and ASTM A959 SS316 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 1570 (Part 7) 6Cr17Ni12Mo2H 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 SS316 is commonly used for marine, chemical, pharmaceutical, food processing equipment.
IS 1570 (Part 7) 6Cr17Ni12Mo2H is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 SS316 is defined under ASTM International, originating from United States.
As per chemical composition, IS 1570 (Part 7) 6Cr17Ni12Mo2H vs ASTM A959 SS316 is a 100% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 100%.
