Close Alternative — 84.9% match
based on chemical composition and mechanical property overlap.
AISI 1025 and BS 970 (Part 1) 045A10 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
AISI 1025 is typically used for forgings, shafts, general engineering, while BS 970 (Part 1) 045A10 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)..
AISI 1025 is defined under AISI, originating from United States, while BS 970 (Part 1) 045A10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, AISI 1025 vs BS 970 (Part 1) 045A10 is a 91.4% 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 84.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
