Strong Match — 89.9% match
based on chemical composition and mechanical property overlap.
IS 4432 10C4 (IS 4432:1988) and BS 970 EN2B (BS 970:1955) are both steel grades.
Both fall under the Carbon Steel category.
IS 4432 10C4 is typically used for forgings and fabrication of case-hardened machine or automobile parts, while BS 970 EN2B is commonly used for bars and billets for forging; forgings and drop-forgings; bars for machining.
IS 4432 10C4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 EN2B is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 4432 10C4 vs BS 970 EN2B is a 89.9% 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 89.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
