Strong Match — 86.2% match
based on chemical composition and mechanical property overlap.
BS 970 EN1A (BS 970:1955) and BS 970 (Part 3) 230M07 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 EN1A is typically used for automatic screw machine parts, bolts, studs, shafts, while BS 970 (Part 3) 230M07 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; free-cutting steel (table 12).
BS 970 EN1A is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 230M07 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN1A vs BS 970 (Part 3) 230M07 is a 86.2% 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 86.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
