Welcome to BBN High Strength Steels Factory
Our company was founded in 2000, which initially committed to providing high-quality steel S690QL materiale products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S690QL materiale steel to the international market, opening up the international steel market.
The full name of 304 stainless steel pipe is SUS304 stainless steel pipe. SUS304 stainless steel pipe belongs to the stainless steel pipe made of American trademark. It is equivalent to Chinese grade 0Cr19Ni9 stainless steel pipe, which is generally replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloy elements form a fine oxide film, which insulates the touch of oxygen and prevents continued oxidation.
The main difference between S690QL materiale, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.
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 S690QL materiale 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 S690QL materiale seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
