Seamless Steel Pipe: Annealing and Non-Annealing

图片
The main difference between   seamless steel pipe   annealing and non-annealing lies in their organizational structure, hardness, machinability, and corrosion resistance. Structural organization and performance transformation: After the seamless steel pipe undergoes annealing treatment, its organizational structure will change. For example, annealing can reduce the hardness of the steel pipe, increase plasticity, enhance machinability, and corrosion resistance. While the steel pipe that has not been annealed may have higher hardness and strength, but it is difficult to process and handle. Annealing types: The annealing of seamless steel pipe includes full annealing, spheroidizing annealing, stress-relief annealing, etc. Full annealing aims to reduce the hardness of seamless steel pipe and eliminate the non-uniform organization and internal stress in the steel. For spheroidizing annealing, the seamless steel pipe needs to be heated to 750 degrees, held for a period of time and ...

The Factors Affecting the Straightness of Seamless Steel Tube

图片
The straightness of   seamless steel tubes   has a significant impact on pipes used in precision machinery and hydraulic cylinders. High straightness accuracy can enhance the efficiency of post-processing for customers and reduce production costs. What are the factors that affect the straightness of seamless tubes?  1. Outdated straightening equipment The outdated straightening equipment, resulting in poor straightening accuracy. The straightness of seamless steel tubes after being discharged from the furnace has not significantly improved, and only visual inspection can ensure no bending. For the precision processing industry, the straightness requirements of such seamless steel tubes cannot be met, for example, for hydraulic cylinders, which have high requirements for the straightness of steel tubes and need to ensure the consistency of the inner hole. However, outdated straightening equipment is far from meeting this requirement.  Xiangjia Steel  possesses ad...
