Q345D DIN2391 H8 Honed Tube Cold Drawing Normalizing Treatment Tube and Piston Cylinder Tube
Honed tubes can be produced according to the demands of customers that the degree of precision can reach H8/H9. Burnishing and honing services can be provided depending on the roughness requirement of inner diameter.
Backed ourselves with talented personnel, we have emerged as one of the leading firms indulged in offering superior quality piston rods. The vital parameters of piston rods such as the diameter tolerance, straightness, surface hardness, chrome layer thickness, as well as surface roughness all meet the industry standards
