Strong Match — 88.5% match
based on chemical composition and mechanical property overlap.
UNI 7845 C45 (UNI 7845:1978) and BS 970 (Part 3) 070M55 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
UNI 7845 C45 is typically used for shafts,axles,gears,studs,bolts,spindles,rollers,general engineering components, while BS 970 (Part 3) 070M55 is commonly used for used for springs, blades, wear plates, hand tools, shafts, and cutting components..
UNI 7845 C45 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy, while BS 970 (Part 3) 070M55 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, UNI 7845 C45 vs BS 970 (Part 3) 070M55 is a 88.5% 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 88.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Used for springs, blades, wear plates, hand tools, shafts, and cutting components.
Can UNI 7845 C45 Be Substituted With BS 970 (Part 3) 070M55?
