Close Alternative — 80.5% match
based on chemical composition and mechanical property overlap.
SAE J404 4047 (SAE J404:2009) and BS 970 (Part 3) 605M36 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4047 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while BS 970 (Part 3) 605M36 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy direct hardening steel (table 16).
SAE J404 4047 is defined under SAE International, originating from United States, while BS 970 (Part 3) 605M36 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, SAE J404 4047 vs BS 970 (Part 3) 605M36 is a 80.5% 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 80.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
