Strong Match — 87.8% match
based on chemical composition and mechanical property overlap.
IS 4432 C10 (IS 4432:1967) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 4432 C10 is typically used for bolts, nuts, shafts, pins, general engineering parts, structural components, welded assemblies, while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
IS 4432 C10 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 4432 C10 vs BS 970 (Part 1) 040A04 is a 87.8% 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 87.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
