ASTM A276/A276M S31000 vs IS 1570 (Part 7) 12Cr12MoH
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
ASTM A276/A276M S31000 (ASTM A276/A276M:2017) and IS 1570 (Part 7) 12Cr12MoH (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A276/A276M S31000 is typically used for stainless steel bars and shapes (hot-finished or cold-finished), 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.
ASTM A276/A276M S31000 is defined under ASTM International, originating from United States, while IS 1570 (Part 7) 12Cr12MoH is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A276/A276M S31000 vs IS 1570 (Part 7) 12Cr12MoH is a 61.4% match.
As per mechanical properties, the match is 0%.
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.
