Strong Match — 90.1% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 230M07 (BS 970 (Part 3):1991) and SAE J403 12L14 (SAE J403:2009) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 (Part 3) 230M07 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; free-cutting steel (table 12), while SAE J403 12L14 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
BS 970 (Part 3) 230M07 is defined under British Standards (BS), originating from United Kingdom, while SAE J403 12L14 is defined under SAE International, originating from United States.
As per chemical composition, BS 970 (Part 3) 230M07 vs SAE J403 12L14 is a 90.1% 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 90.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
