IS 1570 (Part 7) 12Cr9Mo10H vs BS 970 (Part 3) 722M24

Close Alternative — 70.4% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 12Cr9Mo10H (IS 1570 (Part 7):1992) and BS 970 (Part 3) 722M24 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Alloy Steel category. IS 1570 (Part 7) 12Cr9Mo10H is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while BS 970 (Part 3) 722M24 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy direct hardening steel (table 16). IS 1570 (Part 7) 12Cr9Mo10H is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 722M24 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 7) 12Cr9Mo10H vs BS 970 (Part 3) 722M24 is a 70.4% 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 70.4%.
