UGICHROM® 4305

UGICHROM® 4305 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 1.4305, EN X8CrNis18-9, DIN 1.4305, DIN X8CrNis18-9, AISI 303
