A656 steel plate is a high strength low alloy steel plate. A656 steel plate complies with American standard ASTM A656. A656 steel plates are available in three different grades: 50, 60 and 70, each with slightly different strength and mechanical properties.
The chemical composition of A656 steel plate includes the content of elements such as carbon, silicon, manganese, phosphorus, sulfur and chromium. The chemical composition of A656 steel plate mainly includes the following elements:
Carbon (C): 0.18-0.28% max
Silicon (Si): 0.60% max
Manganese (Mn): 1.65% max
Phosphorus (P): 0.025% max
Sulfur (S): 0.035% max
Chromium (Cr): 0.50% max
The composition of A656 steel plate is controlled within a certain range, which can improve its strength, toughness and corrosion resistance, while maintaining good weldability and processability. A656 steel plate is usually manufactured in hot rolling or controlled rolling state, and can be subjected to various forming processes, such as welding, cold bending, cutting, etc.
A656 steel plate has excellent strength, toughness and corrosion resistance, and is widely used in construction, aerospace, military and shipbuilding and other fields. A656 steel plates are commonly manufactured into various structural components such as bridges, building components, vehicles and equipment, etc.
