What is ASTM B348 specification?

Standard specification for ASTM B348 titanium and titanium alloy bars and billets

ASTM B348 is a standard specification from ASTM International that covers the requirements for titanium and titanium alloy bars and billets. This specification outlines the chemical composition, mechanical properties, dimensions, tolerances, and other requirements for various grades of titanium and titanium alloys in the form of bars and billets. Manufacturers and users refer to ASTM B348 to ensure the quality and consistency of titanium materials used in a wide range of industrial applications.

ASTM B348 covers a range of titanium and titanium alloys, including pure grades of titanium (Grades 1 through 4) and various alloyed grades (such as Grade 5, which is Ti 6Al-4V, and Grade 23, which is Ti 6Al-4V ELI). Each grade has specific chemical and mechanical properties suited for different applications.

Application of ASTM B348

Industries that commonly use materials conforming to ASTM B348 include aerospace, medical, chemical processing, marine, and automotive. Engineers, designers, and procurement specialists in these industries rely on the standard to ensure materials meet required performance and quality levels.

ASTM B348 is one of several standards that cover titanium materials. Others include ASTM B265 (for titanium and titanium alloy sheet, strip, and plate) and ASTM F136 (for wrought titanium-6aluminum-4vanadium ELI (extra low interstitial) alloy for surgical implant applications). ASTM B348 specifically deals with bar and billet forms, while each standard addresses different product forms or applications.
