Strong Match — 86.5% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 175H23 (BS 970 (Part 1):1991) and BS 970 (Part 1) 170H20 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 175H23 is typically used for case hardening steel (section four), while BS 970 (Part 1) 170H20 is commonly used for through hardening boron steel (section three).
BS 970 (Part 1) 175H23 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 1) 170H20 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 1) 175H23 vs BS 970 (Part 1) 170H20 is a 86.5% 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 86.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
