Strong Match — 87.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 214A15 (BS 970 (Part 1):1983) and SAE J403 1118 (SAE J403:2014) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 (Part 1) 214A15 is typically used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)., while SAE J403 1118 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
BS 970 (Part 1) 214A15 is defined under British Standards (BS), originating from United Kingdom, while SAE J403 1118 is defined under SAE International, originating from United States.
As per chemical composition, BS 970 (Part 1) 214A15 vs SAE J403 1118 is a 87.4% 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 87.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
