Austenitic Stainless Steel Precision Ground Bars
316Ti Stainless Steel Bar AISI 316Ti | UNS S31635
For components exposed to long-term heat and corrosive media, material stability is critical. By adding titanium to the 316 stainless steel base, 316Ti helps stabilize carbides and reduce the risk of intergranular corrosion during high-temperature service.
This material offers better resistance to intergranular corrosion and improved structural stability compared with standard 316 stainless steel in high-temperature and strongly corrosive environments. It is especially suitable for precision shafts and components used in chemical equipment, high-temperature heat exchange systems, furnace structures, and other parts exposed to continuous thermal stress.
Compass Power Tech manufactures 316Ti stainless steel precision ground bars with stable dimensions, smooth surface quality, and reliable material performance for customers who need corrosion resistance and heat resistance in the same component.

Additional Custom Services
- Cut-to-length service: Shaft length can be customized according to customer assembly requirements.
- End chamfering: Both ends of the shaft can be chamfered to simplify downstream machining and installation.
- Drawing-based machining: Shafts can be machined according to customer drawings and supplied as ready-to-assemble components.
- Surface rolling treatment: Surface rolling can be applied to improve surface hardness when higher wear resistance is required.
Packaging and Storage
To protect stainless steel precision ground shafting during sea freight and storage, Compass Power Tech uses anti-rust paper tube packaging. Before wrapping, anti-rust oil is applied evenly to the shaft surface, and anti-rust wax is applied inside the paper tube. This protection process helps reduce corrosion risk during transportation and ensures customers receive shafts in stable, ready-to-use condition.
