Square cross-section titanium bar — used as-is for structural and machining work, or as starting stock for milling into hexagonal or custom profiles.
Product Overview — Titanium square bars are square cross-section bar stock produced by rolling, forging or machining round bar into a square profile. They are used directly for structural supports and machined components, and also as starting stock for milling into hexagonal or irregular custom profiles. Square bars are less common in standard stock programmes than round bars — availability is confirmed per side dimension and grade.
Long-form note for procurement: In industrial procurement, square titanium bar is often chosen when the component has square dimensions and round bar would require more machining stock removal. If a hexagonal bar or custom profile is also acceptable, square bar can be milled down from, or milled into, the target profile. When inquiring, please state side dimension, length, grade and whether the bar is for direct use or for further milling.
Grade 1, 2, 3, 4 (CP titanium), Grade 5 (Ti-6Al-4V), Grade 7, 9, 11, 12, 16, 17 and Grade 23 (Ti-6Al-4V ELI). Feasibility per side dimension and grade evaluated per inquiry.
Regular square bar stock is limited. Grades and side dimensions held in regular stock are confirmed at inquiry time. Round bar stock is more widely stocked and can be machined to square form.
Some mills supply titanium square bar against ASTM B348 / B348M or a mill-specific specification derived from B348 round bar requirements. Standard applicability to your specific square bar product form, grade and side dimension is confirmed at inquiry time.
Scope note — ASTM B348's formal scope is titanium round bars and billets. It does not automatically cover square bars. Where Feinuotai supplies square bar under B348 alignment, the applicable tolerance and inspection provisions are confirmed together with the quote. If your project requires a specific code or standard reference, please state this in the inquiry.
Processing route options: rolling to square profile (preferred for larger cross-sections), forging + machining, or machining from round bar stock. The most economical route for your side dimension and quantity is confirmed at inquiry time.
Square bar for brackets, supports and frames where square dimensions match the component.
Starting stock for milled and turned parts — used directly or milled into hexagonal or custom profiles.
Square bar is less common for fastener production than round or hexagonal bar, but may be used for special fastener forms.
