Related Material — 65.5% match
based on chemical composition and mechanical property overlap.
EN 10083-1 30CrNiMo8 (EN 10083-1:1996) and BS 970 (Part 1) 835M30 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-1 30CrNiMo8 is typically used for quenched and tempered machine parts (clause 1.1), while BS 970 (Part 1) 835M30 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6..
EN 10083-1 30CrNiMo8 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 835M30 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10083-1 30CrNiMo8 vs BS 970 (Part 1) 835M30 is a 65.5% 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 65.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
