Strong Match — 93.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 070M20 (BS 970 (Part 3):1991) and IS 1570 C20 (IS 1570:1961) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 3) 070M20 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 1570 C20 is commonly used for shafts, studs, pins, forged components, machinery parts, carburized parts.
BS 970 (Part 3) 070M20 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 C20 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 3) 070M20 vs IS 1570 C20 is a 93.8% 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 93.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
