SM520C carbon steel plate sheet with ISO 9001:2000 Certificate

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce SM520C carbon steel plate sheet, hot-rolled seamless steel tube by continuous rolling mill.

The seamless steel pipe for general use is rolled by common carbon structural steel, SM520C carbon steel plate sheet, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.

A 25 percent tariff on imports led to a temporary spike in steel prices last year but also hurt sales and profits at companies that buy steel, such as General Motors. And as manufacturers substituted other materials or cut production, SM520C carbon steel plate sheet steel prices have fallen back to where they were before the tariffs and stock prices for the largest U.S. producers fell by as much as 47 percent, the New York Times reported Monday.
