Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
SAE J404 50B46 (SAE J404:2000) and BS 970 EN21A (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 50B46 is defined under SAE International, originating from United States, while BS 970 EN21A is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, SAE J404 50B46 vs BS 970 EN21A is a 74.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
