What Are Stainless Steel 316Ti Fasteners?
Stainless Steel 316Ti is a titanium-stabilized version of 316 stainless steel. Titanium combines with carbon to minimize chromium carbide precipitation during certain elevated-temperature conditions. This makes 316Ti particularly useful for components exposed to heat and corrosive environments.
Our Titanium Stabilized 316Ti Fasteners can be supplied in various forms, including:
- SS 316Ti Hex Bolts and Nuts
- SS 316Ti Heavy Hex Bolts
- UNS S31635 Stud Bolts
- SS 316Ti Stud Bolts
- 316Ti SS Threaded Rod
- SS 316Ti Socket Head Cap Screws
- Machine screws and tapping screws
- Washers and custom fasteners
- Special and non-standard fasteners
Fasteners can be manufactured or supplied according to applicable ASTM, ASME, DIN, BS, JIS and other project specifications, subject to grade, size and product requirements.
