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.
Grade 630 stainless steels are martensitic stainless steels that are precipitation hardened to achieve excellent mechanical properties. These steel achieve high strength and hardness following heat treatment. The heat and corrosion resistance of grade 630 are similar to that of grade 304 steels. This grades is also commonly referred to as grade 17-4PH.
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.
