4.What's your main products?
(1)Seamless steel tube, carbon steel 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 STKM11A STKM13A SAE4130 4140
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, SRB 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 inside tube more smooth which can be used for cylinder directly.
