S355ML carbon steel plate sheet equivalent grade

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S355ML carbon steel plate sheet, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

According to the data of the Bureau of statistics, the average monthly output of domestic S355ML carbon steel plate sheet and so on steel in the past five years (2015-2019) is 96.8696 million tons. In recent five years (2015-2019), the average monthly export volume of domestic steel is 7.2152 million tons, accounting for 7.45% of the average monthly steel output. The top 10 major exporters are South Korea, Vietnam, Thailand, Indonesia, the Philippines, India, Myanmar, Saudi Arabia, the United Arab Emirates and Malaysia, accounting for 51.4% of the total domestic exports.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the S355ML carbon steel plate sheet steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of S355ML carbon steel plate sheet seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
