Classification of steel tubes

1.Seamless steel tube, seamless pipe
Widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT, ST52, CK45 and AISI 1020. We can also offer as customized seamless steel tube.

2.cold drawn steel tube/cold rolled steel tube
Grade: 20#  45#  16Mn  25Mn  27SiMn  E355  ST52 S45C STKM11A STKM13A
Standard: GB/T8713  GB/T3639  DIN2391  EN10305  ASTMA519
Range: 30-300mm
Length: 11m(max)
The cold process can change the thickness of tube to meet client's request and offer better mechanical property.

3. Honed steel tube, honed tube, honed steel pipe
ID Tolerance: H8  H9
ID Roughness: RA0.4micron(max)
Length: 6m(max)
Inner roughness: Ra0.2-0.8um
Straightness: 1:1000 or customized
This process can improve the roughness of the inner tube to 0.2-0.8um and make inside tube more smooth which can be used for cylinder directly.
