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
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)
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.
