A572 Gr.42 Steel Description

ASTM A572 Gr42 carbon steel belongs to high-strength low alloy niobium vanadium structural steel plate, which complies with ASTM A572/A572M American standard. The A572 Grade 42 low alloy high-strength structural steel plate has high strength, high toughness, fatigue resistance, impact resistance, abrasion resistance, earthquake resistance, corrosion resistance and other high-quality properties. The low carbon content ASTM A572 Gr42 carbon steel plate can minimize the carbide precipitation during welding to maintain the corrosion resistance of welded structures. A572 Gr42 steel plate is applicable to the manufacture of bridge riveted and bolted components or other riveted, bolted or welded components.

A572 Gr42 low alloy high-strength structural steel is equivalent to S275 J2G3 and S275NL materials. A572 Gr42 steel plate is widely used in engineering structures, such as building steel structures, construction machinery, mining machinery, heavy trucks, bridges, pressure vessels, etc., especially for building and engineering machinery parts that require good weldability and toughness.

Heat treated : 1538°C - 1213°C
