Manufacturing method of 12Cr1MoVR alloy: This plate is melted in oxygen top blown converter, open hearth furnace or electric furnace. After negotiation with the demander, other equivalent methods can also be adopted. GL-EH 32 car carrier steel, 12Cr1MoVR alloy steel plate is usually delivered in normalized + tempered state. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in Annealed or tempered state.

Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, GL-EH 32 car carrier steel and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the GL-EH 32 car carrier steel steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
