Heavy and Thick Plate
SM400A corresponds to China's national standard Q235D. This means that although SM400A and Q235D are both carbon structural steels, they differ in certain performance parameters. For example, the tensile strength requirement for SM400A is above 400 MPa, while the yield strength requirement for Q235D is above 235 MPa.
Chemical composition and properties of SM400A
The specific chemical composition range of SM400A is as follows: C ≤ 0.23%, Si≤0.035%，Mn≥2.5%，P≤0.035%，S≤0.035%。 Its performance includes being easy to weld and also belongs to the category of welded structural steel.
SM400A steel plate is widely used and can be found in various industries such as aerospace, power, petrochemicals, shipbuilding, machinery, electronics, and environmental protection.
