Close Alternative — 73.6% match
based on chemical composition and mechanical property overlap.
BS 970 EN363 (BS 970:1955) and SAE J404 8625 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN363 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for tensile strength 65 tons/sq in min. supplied on tensile strength only or, by special arrangement, on analysis only., while SAE J404 8625 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
BS 970 EN363 is defined under British Standards (BS), originating from United Kingdom, while SAE J404 8625 is defined under SAE International, originating from United States.
As per chemical composition, BS 970 EN363 vs SAE J404 8625 is a 73.6% 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 73.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
