Close Alternative — 79.4% match
based on chemical composition and mechanical property overlap.
BS 970 EN36C (BS 970:1955) and BS 970 EN38 (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN36C is typically used for used for gears, camshafts, pinions, heavy-duty shafts, aerospace transmission parts, and worm drives., while BS 970 EN38 is commonly used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for tensile strength of 65 tons/sq in min..
BS 970 EN36C is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN38 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN36C vs BS 970 EN38 is a 69% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a close alternative overall at 79.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
