Titanium Discs Direct From The Factory - High Quality & Competitive Prices!

Titanium disc

Titanium disc is usually used to make heat exchanger titanium tubesheet or to be machined into titanium flange, etc. As a company with more than 20 years of production experience, we have a series of rigorous forging process and operation manual, including the heating steps, heating time and heat preservation time. The 35MN and 16MN rapid forging machine guaranteed the multiple forging in the suitable temperature range. And the forging technology could change the physical structure of titanium disc. Greatly improved the quality of titanium disc level.
