Strong Match — 95.7% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 080M30 (BS 970 (Part 3):1991) and BS 970 EN5D (BS 970:1955) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 3) 080M30 is typically used for used for shafts, gears, axles, couplings, bolts, and general engineering components., while BS 970 EN5D is commonly used for bars for machining.
BS 970 (Part 3) 080M30 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN5D is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 3) 080M30 vs BS 970 EN5D is a 95.7% 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 95.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
