SUS304 AISI 304 1.4301 Stainless Steel Hydraulic Piston Rod

the rods first undergo precision milling and processing, and are then put through grind surface chromium treatment, allowing a surface precision level of f8, and a surface hardness reaching HV850 minimum and up, which not only help to improve wear resistance but also help to extend the life cycle of the rods, thus helping the customer save cost.

Directly for cylinder, cylinder, shock absorber piston rod, and is widely used in textile printing and dyeing, printing machinery, guide rail, die-casting machine, injection molding machine guide rod, the ejector and other mechanical products of guide pin and four-column press guide post, fax machines, printers and other modern office machinery guide shaft and some precision slender shaft for the parts industry products.
