Carbon Precision Seamless Steel Tube For Shock Absorbers
Carbon Precision Seamless Steel Tube Steel Tube for Shock Absorbers
Cold-rolled (dial) seamless steel pipe is divided into general steel pipe, low and medium pressure boiler
steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe,
other steel pipes, and also includes carbon thin-walled steel pipe and alloy thin-walled steel pipe. Stainless
steel thin-walled steel pipe and special-shaped steel pipe. The outer diameter of hot-rolled seamless pipe
is generally larger than 32mm, the wall thickness is 2.5-75mm, the outer diameter of cold-rolled seamless
steel pipe can be up to 6mm, the wall thickness can be up to 0.25mm, the outer diameter of thin-walled pipe
can be 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
