UGICHROM® 4057
UGICHROM® 4057 introduction
UGICHROM® is the result of combining the high efficiency of micro-fissuring chromium plating with the technology of the most advanced stainless steel bars. The UGICHROM® product range is recommended for hydraulic and pneumatic mechanisms.
General properties - choice for performance:
Low friction coefficient.
High resistance to wear.
Increased corrosion resistance.
Micro-fissuring chromium plating guarantees excellent performance under extreme conditions of service.
Improved machinability (up to +20% of productivity).
High mechanical properties.
Accurate geometrical and dimensional properties..
Equivalent material: EN 1.4057, DIN 1.4057, AISI 431, EN X17CrNi16-2, DIN X17CrNi16-2
