EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe

Description

EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe is processed through cold drawing and hot rolling, achieving high precision and strength, making it suitable for mechanical structural components and hydraulic equipment. Hydraulic Cylinder Honed Steel Pipe is available in a wide range of specifications, with inner diameters ranging from 20mm to 400mm and wall thicknesses ranging from 3mm to 50mm.

EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe is processed through skiving and rolling, which improves the surface corrosion resistance of the steel pipe and delays the initiation and propagation of fatigue cracks, thereby enhancing the fatigue strength of the EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe. Rolling forms a cold-work-hardened layer on the steel pipe surface, reducing elastic and plastic deformation at the contact surface of the grinding pair, thereby improving the wear resistance of the honed pipe inner wall. Rolling also reduces surface roughness, improving fit properties.

EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe Applications:

E355 honed steel pipe is primarily used in the manufacture of hydraulic system components (such as cylinders and oil cylinders), pneumatic components, and heavy machinery structural parts, suitable for applications in the petrochemical, aerospace, and other fields.

Specific Applications
Hydraulic Systems: Used in the manufacture of hydraulic components such as cylinders for machine tools and excavators, featuring high-precision internal bores and high-pressure resistance.

Pneumatic Components: As key components of cylinders, they feature high precision and corrosion resistance.

Industrial Piping: Suitable for pipelines in petrochemical equipment, meeting corrosion resistance and high-pressure requirements.

Heavy Machinery Structural Parts: Used in the manufacture of high-strength components such as chassis and booms for heavy machinery.

Material Properties
EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe offers high strength (yield strength ≥ 355 MPa), good toughness, and corrosion resistance. The honing process improves surface precision and wear resistance, making it suitable for use in extreme operating conditions.
