Welcome to BBN High Strength Steels Factory
The use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight. It must be noted that for components that may be bent, the allowable stress must be corrected to ensure the robustness of the structure. Sometimes low-alloy high-strength steel is used to replace 1.8933 steel equivalent, carbon structural steel without changing the cross-sectional size. Its sole purpose is to obtain a stronger and more durable structure without increasing weight.
The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
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 1.8933 steel equivalent 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 1.8933 steel equivalent seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, 1.8933 steel equivalent tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
