Strong Match — 95.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 150M19 (BS 970 (Part 3):1991) and IS 4367 20C15 (IS 4367:1991) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 3) 150M19 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13), while IS 4367 20C15 is commonly 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.
BS 970 (Part 3) 150M19 is defined under British Standards (BS), originating from United Kingdom, while IS 4367 20C15 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 3) 150M19 vs IS 4367 20C15 is a 95.4% 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 95.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
