A36 steel plate is one of the common steel, have you ever known about it?
Now follow me on a journey of discovery about A36 steel!
ASTM-A36 steel plate is an American standard carbon structural steel produced according to ASTM standards. A36 carbon steel coil chemical composition and mechanical properties comply with American ASTM standards. Hot rolling is used as the basic delivery state, and the production thickness is between 2mm and 400mm. The technical requirements of steel plates can refer to the A578 American flaw detection standard. There are three flaw detection levels A, B, C and A435 level flaw detection. A36 hot rolled steel performance is stable for production. A36 hot rolled steel plate has good mechanical properties, welding performance and corrosion resistance, and is widely used in construction, bridges, machinery manufacturing and other fields.
ASTM-A36 is a type of carbon steel whose chemical composition is mainly composed of carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. Among them, carbon is the main element, and its function is to increase the strength and hardness of steel. Silicon and manganese are alloying elements that further increase the strength and hardness of steel. Phosphorus and sulfur are impurity elements. Their presence will reduce the toughness and corrosion resistance of steel, so their content needs to be strictly controlled during the production process.
C：≤0.25%
Si：≤0.4%
Mn：≤0.8-1.2%
P：≤0.04%
S：≤0.05%
Cu：≤0.2%
ASTM-A36 has excellent mechanical properties, including high strength, high toughness, good plasticity and processing properties. Its tensile strength is 160ksi (1150MPa), yield strength is 145ksi (1050MPa), elongation is 22% (2-inch gauge), and section shrinkage is 45%. These mechanical properties give ASTM-A36 high load-bearing capacity and seismic resistance in various engineering applications.
Yield strength——≥360MPa
Tensile strength——400MPa-550MPa
Elongation after break——≥20%
The manufacturing process of A36 steel plate mainly includes continuous casting, hot rolling, cold rolling, annealing and other processes. First, the raw materials are smelted into steel billets at high temperatures, and then continuously cast to obtain steel ingots. Then, the steel ingot is hot rolled and cold rolled to obtain the steel plate with the required specifications. Finally, the steel plate is annealed to eliminate internal stress and improve the mechanical properties and stability of the steel plate. In addition, in order to improve the surface quality and precision of the steel plate, processes such as flattening, straightening, and precision cutting are also required.It can produce A36 carbon steel coil,A36 checkered plate,A36 hot rolled steel plate etc.
ASTM-A36 steel plates are widely used in various engineering fields, such as construction, bridges, machinery manufacturing, etc.
