Strong Match — 94.2% match
based on chemical composition and mechanical property overlap.
BS 970 EN5B (BS 970:1955) and BS 970 (Part 3) 080A30 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN5B is typically used for mechanical properties are not part of the contractual obligations of specifications en 5a, en 5b and en 5c., while BS 970 (Part 3) 080A30 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13).
BS 970 EN5B is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 080A30 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN5B vs BS 970 (Part 3) 080A30 is a 94.2% 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 94.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
