Strong Match — 90% match
based on chemical composition and mechanical property overlap.
BS 970 EN110 (BS 970:1955) and BS 970 EN24 (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN110 is typically 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), 70/80 (w) tons/sq in according to ruling section. capable of meeting the test requirements of en 16, en 17 and en 19., while BS 970 EN24 is commonly used for heavy duty gears, shafts, connecting rods.
BS 970 EN110 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN24 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN110 vs BS 970 EN24 is a 85% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 90%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
