Strong Match — 89.4% match
based on chemical composition and mechanical property overlap.
BS 970 EN42C (BS 970:1955) and BS 970 EN49D (BS 970:1955) are both steel grades.
Both fall under the Spring Steel category.
BS 970 EN42C is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN49D is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN42C vs BS 970 EN49D is a 89.4% 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 89.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Can BS 970 EN42C Be Substituted With BS 970 EN49D?
BS 970 EN42C and BS 970 EN49D overlap closely enough on chemistry and mechanical properties that BS 970 EN49D is often considered as a substitute for BS 970 EN42C in many applications. Always confirm the specific property range your application needs before substituting, and check with your supplier's mill certificate.
