GCr15 seamless steel pipe is a high carbon chromium bearing steel with less alloy content, good performance and wide application. After quenching and tempering, it has high and uniform hardness, good ...

(1) Raw materials are strip coils, welding wire, flux. Strict physical and chemical testing is required before input. (2) The steel head and tail are butt jointed, and the single wire or double wir...

Seamless steel tubes are pided into hot-rolled (extruded) seamless steel tubes and cold drawn (rolled) seamless steel tubes due to their different manufacturing processes. Cold drawn (rolled) tubes ar...

The stainless steel tube does not easily rust and has a great relationship with the composition of the stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon, an...

Galvanized steel pipe has the advantages of corrosion resistance, long service life, and the price of galvanized steel pipe is correspondingly low, so its usage rate is now higher and higher. But when...

In the production of seamless steel tubes, regular holes and pits are mainly caused by uneven deformation. The key to solving the problem lies in reducing uneven deformation. In order to solve this pr...

There are now more and more types of vehicles, and seamless steel tubes play an important role in the manufacture of vehicles. For example, the application of seamless steel pipe in vehicles mainly re...

The seamless steel pipe is expressed by the method of outer diameter, wall thickness and thick-walled seamless pipe, which are mainly used for mechanical processing, coal mine, hydraulic steel and the...

The seamless steel pipe is a steel pipe without weld seams produced by a perforated hot rolling method. It is sometimes necessary to further cold work the hot worked tube in order to obtain the corres...

The seamless steel tube is bent because the rolling mill is not properly adjusted, the residual stress remaining during rolling, and the unequal cooling due to the cross-section and length of the tube...
