What are the advantages and disadvantages of Chinese grade 45 seamless steel pipe

Advantages of Chinese grade 45 seamless steel pipe:
1. Chinese grade 45 seamless steel pipe enjoys high forming speed and high output. It can be made into a variety of cross-sections to meet the needs of the conditions.

2. The cold rolling process can produce a great plastic deformation, thus increasing the yield point of Chinese grade 45 seamless steel pipe.

3. Chinese grade 45 seamless steel pipe has high precision, which can reduce the material waste.

Disadvantages of Chinese grade 45 seamless steel pipe:
1. There is residual stress in the section of Chinese grade 45 seamless steel pipe, which affects the global and local buckling characteristics of Chinese grade 45 seamless steel pipe;

2. The free torsion stiffness of Chinese grade 45 seamless steel pipe is low;

3. The wall thickness of Chinese grade 45 seamless steel pipe is small, and its ability to bear local concentrated load is weak.
