ASTM A572 Gr.65 vs AS/NZS Grade 500

Strong Match — 90.8% match based on chemical composition and mechanical property overlap.

ASTM A572 Gr.65 (ASTM A572) and AS/NZS Grade 500 (AS/NZS 3597:2008) are both steel grades. Both fall under the Structural Steel category. ASTM A572 Gr.65 is typically used for used for bridges, buildings, transmission towers, construction equipment, offshore structures, and structural members., while AS/NZS Grade 500 is commonly used for heavy mining equipment, bulldozer blades, wear-resistant structural applications, large crane booms, offshore jackets.. ASTM A572 Gr.65 is defined under ASTM International, originating from United States, while AS/NZS Grade 500 is defined under Australian/New Zealand Standard (AS/NZS), originating from Australia/New Zealand.

As per chemical composition, ASTM A572 Gr.65 vs AS/NZS Grade 500 is a 90.8% 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 90.8%.
