Strong Match — 88.4% match
based on chemical composition and mechanical property overlap.
EN 10083-3 34CrS4 (EN 10083-3:2006) and BS 970 (Part 1) 530A32 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-3 34CrS4 is typically used for quenched and tempered, flame or induction hardened machine parts (clause 1), while BS 970 (Part 1) 530A32 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6..
EN 10083-3 34CrS4 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 530A32 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10083-3 34CrS4 vs BS 970 (Part 1) 530A32 is a 88.4% 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 88.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
