Close Alternative — 76.1% match
based on chemical composition and mechanical property overlap.
BS 970 EN361 (BS 970:1955) and SAE J404 8615 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN361 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for tensile strength 45 tons/sq in min., while SAE J404 8615 is commonly used for used for gears, pinions, shafts, bushings, transmission parts, and heavy-duty machinery components..
BS 970 EN361 is defined under British Standards (BS), originating from United Kingdom, while SAE J404 8615 is defined under SAE International, originating from United States.
As per chemical composition, BS 970 EN361 vs SAE J404 8615 is a 76.1% 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 76.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
