The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. SA588 Grade B low alloy steel, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of SA588 Grade B low alloy steel structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our SA588 Grade B low alloy steel, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.
