Strong Match — 100% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 805M22 (BS 970 (Part 1):1991) and BS 970 (Part 1) 805H22 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 805M22 is typically used for case hardening steel (section four), while BS 970 (Part 1) 805H22 is commonly used for case hardening steel (section four).
BS 970 (Part 1) 805M22 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 1) 805H22 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 1) 805M22 vs BS 970 (Part 1) 805H22 is a 100% 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 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
