Product show of carbon tube
1.Seamless steel tube and carbon tube
Widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT STKM13A ST52 CK45 E355 and AISI 1020. We can also offer as customized seamless steel tube.
2.cold drawn steel pipe/cold rolled steel tube
Grade: 20# 45# 16Mn 25Mn 27SiMn E355 ST52 CK45 STKM11A STKM13A STKM13C
Standard: GB/T8713 GB/T3639 DIN2391 EN10305 ASTMA519
Range: 30-300mm
Length: 11m(max)
The cold process can remove the oxide layer outside to improve surface and offer better mechanical property.
3. Honed Tube&SRB steel pipe, honed steel pipe
ID Tolerance: H8 H9 or as client's request
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 tube for cylinder using directly.
