45# precision steel pipe
use:
Manufacturing steel sleeves and hydraulic cylinders.
chemical composition:
The carbon (C) content is 0.42~0.50%, the Si content is 0.17~0.37%, the Mn content is 0.50~0.80%, and the Cr content is <=0.25%.
Heat treatment process:
The heat treatment of 45# precision steel pipe is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the 45# precision steel pipe, but by changing the microstructure inside the 45# precision steel pipe. Organize or change the chemical composition of the surface of 45# precision seamless steel pipe to give or improve the performance of the workpiece. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye.
