Product Description
Product introduction | ||||||||||||||||
Seamless steel tube products for machining use tube blanks (mainly continuous casting blanks) as raw materials, which are heated and rolled into steel tubes by centering, piercing, continuous rolling and tension reduction units. At the same time, the supporting production equipment such as tube end thickening, pipe joint processing, tool joint processing, heat treatment, ultrasonic, magnetic flux leakage, eddy current, magnetic particle on-line flaw detector, spectrum and hardness tester can meet the various requirements of different users. | ||||||||||||||||
Chemical composition of pipes for machining; | C 0.08~0.19 Mn 0.40~0.70 Si 0.17~0.37 S ≤0.035 P ≤0.035 Cr 0.40~0.70 Mo 0.40~0.55 Ni ≤0.30 | |||||||||||||||
Performance of pipes for machining; | Tensile strength)MPa:410~560 ~ 560 Yield point MPa:205 Elongation (%): 2 | |||||||||||||||
The purpose of the pipe for machining: | Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsion strength is the same, and it is an economic cross-section steel, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipes, bicycle racks and steel scaffolding used in construction. | |||||||||||||||
