Close Alternative — 79.1% match
based on chemical composition and mechanical property overlap.
BS 970 EN24 (BS 970:1955) and BS 970 EN23 (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN24 is typically used for heavy duty gears, shafts, connecting rods, while BS 970 EN23 is commonly used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for 50/60 (s), 55/65 (t), 60/70 (u), 65/75 (v) tons/sq in according to ruling section..
BS 970 EN24 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN23 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN24 vs BS 970 EN23 is a 68.6% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a close alternative overall at 79.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
