Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
EN 10084 10NiCr5-4 (EN 10084:2008) and BS 970 EN111A (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 10NiCr5-4 is defined under European Standard (EN), originating from Europe, while BS 970 EN111A is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10084 10NiCr5-4 vs BS 970 EN111A is a 75% 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.
