Product Detail
Product Introduction
Titanium round bar and titanium round rod are common commercial descriptions for the same solid circular wrought product. Supply is defined by the invoked material specification, titanium grade, diameter, length, condition, dimensional tolerance, straightness, surface and certification—not by choosing between the words bar and rod. ASTM B348 / ASME SB348 is commonly specified for titanium and titanium-alloy bar and billet; aerospace, medical or regional specifications must be stated expressly when required.

FAQ
Are titanium round bar and titanium round rod different products?
Usually no. In commercial use both names commonly refer to solid circular stock. The controlling requirements are the grade, product specification, diameter, length, condition, tolerance, surface and inspection.
What information is needed to quote titanium round bar?
Provide grade and UNS designation, governing standard and revision, diameter, length, quantity, condition, surface, tolerance, straightness, tests, certificates and destination.
Can titanium round bar be supplied for machining?
Yes. State the finished-part envelope, machining allowance, cut-length tolerance, straightness, surface condition and any ultrasonic or dimensional inspection needed for the component.
