Close Alternative — 74.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 212M36 (BS 970 (Part 1):1983) and SAE J403 1126 (SAE J403:2014) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 (Part 1) 212M36 is typically used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6., while SAE J403 1126 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
BS 970 (Part 1) 212M36 is defined under British Standards (BS), originating from United Kingdom, while SAE J403 1126 is defined under SAE International, originating from United States.
As per chemical composition, BS 970 (Part 1) 212M36 vs SAE J403 1126 is a 74.8% 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 74.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
