IS 1570 (Part 2/Sec 1) 40C8 vs BS 970 (Part 1) 080H41

Strong Match — 96% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 40C8 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 080H41 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 40C8 is typically used for hardened and tempered parts, cold rolled medium and high carbon strip and hot rolled bars for bright bars and machined parts (the standard links this grade to is 5517, is 7226, is 7283), while BS 970 (Part 1) 080H41 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6.. IS 1570 (Part 2/Sec 1) 40C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 080H41 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 2/Sec 1) 40C8 vs BS 970 (Part 1) 080H41 is a 96% 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 96%.
