ASTM A572 Grade 50 Steel Plate — Factory Direct Supplier | Huaxia-Steel
Huaxia-Steel supplies ASTM A572 Grade 50 steel plate for construction, bridges, truck frames, and heavy machinery. As a high-strength low-alloy (HSLA) grade, A572 Gr.50 offers higher yield strength than A36 while maintaining good weldability and formability.
Product Overview
ASTM A572 Grade 50 is a columbium-vanadium structural steel plate. It provides a minimum yield strength of 50 ksi (345 MPa) and is widely used in welded bridges, buildings, and general structural applications where weight reduction is important.
We supply A572 Grade 50 plate in rolled, normalized, and thermo-mechanically controlled process (TMCP) conditions. Custom cutting, beveling, and drilling are available.
