Close Alternative — 80.4% match
based on chemical composition and mechanical property overlap.
AS/NZS 3678 Grade 400 (AS/NZS 3678:2016) and ASTM A572/A572M Grade 60 (ASTM A572/A572M:2021) are both steel grades.
Both fall under the Structural Steel category.
AS/NZS 3678 Grade 400 is typically used for heavy structural fabrication, crane booms, mining machinery, earthmoving equipment, structural columns., while ASTM A572/A572M Grade 60 is commonly used for riveted or bolted bridge construction, or riveted, bolted or welded construction in other applications.
AS/NZS 3678 Grade 400 is defined under Australian/New Zealand Standard (AS/NZS), originating from Australia/New Zealand, while ASTM A572/A572M Grade 60 is defined under ASTM International, originating from United States.
As per chemical composition, AS/NZS 3678 Grade 400 vs ASTM A572/A572M Grade 60 is a 95.6% match.
As per mechanical properties, the match is 50%.
Combined, this makes them a close alternative overall at 80.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
