SA572 Gr.50 High Strength Alloy Structural Steel

SA572 Gr.50 alloy steel is a high-strength low-alloy niobium-vanadium structural steel plate, equivalent to domestic grade Q345.

SA572 Gr.50 alloy steel plate executive standard: ASTM A572/A572M

SA572GR is divided into five grades:
Grade 42 (290), Grade 50 (345), Grade 55 (380) for riveted, bolted or welded structures
Grades 60 (415) and 65 (450) are used for riveted and bolted structures in bridges or welded structures for other purposes.
