Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of
GB/T222 Alloy composition: type 1: Nb: 0.005~0.05 Type
2: V: 0.01~0.15 Type
3: Nb: 0.005~0.05, V: 0.01~0.15, Nb+V:
0.02~0.15
Type 5: Ti: 0.006~0.04, N: 0.003~0.015, V: ≤0.06
steel requires the addition of niobium, vanadium, titanium or nitrogen, or a combination thereof, within the scope of the above provisions. Unless otherwise specified, the choice of steel type (Type 1, 2, 3 or 5) is at the discretion of the manufacturer.
6. Application scope of SA572Gr50:
SA572Gr50 low-alloy high-strength structural steel plate is widely used in engineering structures, such as construction steel structures, construction machinery, mining machinery, trucks, bridges, pressure vessels, etc., especially for construction and construction machinery components that require good weldability and toughness
