Hot-rolled seamless steel pipe deformed processes
Hot-rolled seamless steel pipe production base deformation process can be summarized as three stages: perforation, extension and finishing. The main purpose of the perforation process is to become a solid round billet piercing hollow shell. Capillary in the specifications, accuracy and surface qu...Read more -
Heat treatment defects
Heat treatment can improve the processing performance of steel to improve its performance, significantly improve the mechanical properties of steel, and extend its life. Dynamic load and friction in a variety of work under conditions of gears, crankshafts and other parts, they require the surface...Read more -
Galvanized carbon steel
Galvanized carbon steel is steel that has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish that many people f...Read more -
