Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of A633 Grade C meaning these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

What are the general uses of A633 Grade C meaning, low alloy steel plate? First, low alloy steel plate can be used as bridge steel plate, because it has strong bearing capacity. The bridge’s daily traffic flow is very large, so it must have very good bearing capacity. Second, because low alloy steel plate has good toughness and is easy to process, it is often used to manufacture ships and vehicles. Thirdly, the use of low alloy steel plate is indispensable to the construction of some frame structure workshops. Because of the low alloy content, low alloy steel plate has its own characteristics.

"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, A633 Grade C meaning tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
