Close Alternative — 75.3% match
based on chemical composition and mechanical property overlap.
BS 970 EN58J (BS 970:1955) and ASTM A959 317 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN58J is defined under British Standards (BS), originating from United Kingdom, while ASTM A959 317 is defined under ASTM International, originating from United States.
As per chemical composition, BS 970 EN58J vs ASTM A959 317 is a 75.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 75.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
