Strong Match — 85.2% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 905M39 (BS 970 (Part 1):1991) and BS 970 EN41C (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 905M39 is typically used for steel for surface hardening by nitriding (section three), while BS 970 EN41C is commonly used for precision nitrided components, gauges.
BS 970 (Part 1) 905M39 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN41C is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 1) 905M39 vs BS 970 EN41C is a 85.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 85.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
