ASTM B348-09

Standard Specification for Titanium and Titanium Alloy Bars and Billets

ABSTRACT
This specification covers annealed bars and grills made from titanium or its alloys. All material grades covered should conform to the required chemical composition requirements. Elements that are intentionally added to the melt should be identified, analyzed and reported in the chemical analysis. Specimens for tension tests should be machined and the tensile properties determined using a specified strain rate through the yield strength and at an increasing rate. Each annealed material may be furnished as either descaled, sandblasted, ground, or rough turned.
