What is the BBNSteel ASTM A387 Gr.11 Cl2 boiler plate application

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. ASTM A387 Gr.11 Cl2 boiler plate, 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.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The ASTM A387 Gr.11 Cl2 boiler plate cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

According to the data of the National Bureau of statistics, from January to February, the output of pig iron, crude steel and steel (excluding repetitive materials) were 132.34 million tons, 154.7 million tons and 167.13 million tons, respectively, up 3.1%, 3.1% and 3.4% year on year; the daily output of ASTM A387 Gr.11 Cl2 boiler plate, crude steel was 2.5783 million tons, down 5.15% year on year.
