Close Alternative — 77.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 945M38 (BS 970 (Part 1):1983) and BS 970 (Part 1) 805A22 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 945M38 is typically used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6., while BS 970 (Part 1) 805A22 is commonly used for case hardening steel (section four).
BS 970 (Part 1) 945M38 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 1) 805A22 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 1) 945M38 vs BS 970 (Part 1) 805A22 is a 77.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 77.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
