Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 EN56C (BS 970:1955) and ASTM A959 .- (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN56C is defined under British Standards (BS), originating from United Kingdom, while ASTM A959 .- is defined under ASTM International, originating from United States.
As per chemical composition, BS 970 EN56C vs ASTM A959 .- is a 70.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
