IS 4367 20C15 vs BS 970 (Part 1) 150M19

Strong Match — 90.7% match based on chemical composition and mechanical property overlap.

IS 4367 20C15 (IS 4367:1991) and BS 970 (Part 1) 150M19 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Carbon Steel category. IS 4367 20C15 is typically used for low-carbon case-hardening (carburizing) steel; used for lightly stressed components such as pins, bushes, and small shafts requiring a hard wear-resistant surface with a tough core, while BS 970 (Part 1) 150M19 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6.. IS 4367 20C15 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 150M19 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 4367 20C15 vs BS 970 (Part 1) 150M19 is a 90.7% 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 90.7%.
