ST52 E355 Hollow Steel Tube Hydraulic Cylinder Honed Pipe

ST52 E355 Hydraulic Cylinder Honed Tube

  • It has general corrosion resistance similar to unstable ni-cr304.
  • It has high temperature oxidation resistance, but the oxidation rate will be affected by internal factors such as exposure environment and product morphology.
  • The total heat transfer coefficient of metal depends on the thermal conductivity of metal, but also on other factors. Stainless steel keeps the surface clean, so it can conduct electricity. Metals with higher thermal conductivity have better heat dissipation than other metals

 

Description:

Delivery conditions

1. NBK(+N)

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

2. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C)

the final heat treatment after cold forming, therefore small steel pipe plastic, the plastic degree does not guarantee

4. BKW(+LC)

after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)
