Standard Specification for Titanium and Titanium Alloy Bars, Billets, and Forgings For General Industrial & Aerospace Use
Standard Overview
ASTM B348 is a core international standard published by ASTM International, covering titanium and titanium alloy bars, billets, and forgings for a wide range of industrial and aerospace applications. This standard complements ASTM B265 (flat products) by focusing on long products including bars, rods and forgings, specifying comprehensive requirements for chemical composition, mechanical properties, testing and quality assurance for all common titanium grades.
ASTM B348 is the most widely referenced standard for titanium bar and forging products globally, serving as a universal benchmark for material quality and acceptance. All titanium bar and forging products from BOZE Metal fully comply with ASTM B348, catering to diverse customer needs from general industrial to high-performance aerospace applications.
Standard Scope & Applicable Grades
ASTM B348 applies to hot-rolled, cold-finished, and forged titanium bars, billets, rods, and forgings, covering all commercially pure titanium and titanium alloy grades supplied by BOZE Metal, suitable for machining, forging and structural applications.
- Commercially Pure Grades: Grade 1, 2, 3, 4, 7, 11, 12
- Titanium Alloy Grades: Grade 5, Grade 9, Grade 23 (Ti-6Al-4V ELI)
- Product Forms: Titanium bars, rods, billets, forgings, machined components
Key Standard Requirements
- Unified chemical composition requirements for all titanium grades, ensuring material consistency
- Specific mechanical property benchmarks for each grade, including tensile and yield strength
- Dimensional tolerances for diameter, length, straightness and surface finish
- Non-destructive testing requirements for critical diameter bars and forgings
- Heat treatment guidelines and material condition standards (annealed, heat treated)
- Standardized testing methods for quality verification and material certification
Industrial & Aerospace Applications
- CNC Machining: Raw material for precision machined parts, fasteners, fittings
- Industrial Equipment: Mechanical components, shafts, brackets, structural parts
- Aerospace Components: Bar stock for aircraft parts, forged aerospace components
- Medical Industry: Raw material for non-implantable and implantable medical components (Grade 23)
- Marine & Chemical: Corrosion-resistant bars for marine and chemical processing equipment
