Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 1570 C30 (IS 1570:1961) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 1570 C30 is typically used for axles, shafts, gears, connecting rods, machine parts, forgings, while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
IS 1570 C30 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 1570 C30 vs BS 970 (Part 1) 040A04 is a 78.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
