Strong Match — 91.2% match
based on chemical composition and mechanical property overlap.
BS 970 EN43A (BS 970:1955) and BS 970 (Part 3) 080A47 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN43A is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable hardened and tempered for 45/55 (r) and 50/60 (s) tons/sq in according to ruling section; purchaser to state normalised, cold drawn or hardened and tempered r or s. en 43a to 43e., while BS 970 (Part 3) 080A47 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 EN43A is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 080A47 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN43A vs BS 970 (Part 3) 080A47 is a 91.2% 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 91.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
