Q: What makes Titanium fasteners per ASTM B348 unique?
A: ASTM B348 is a specification that applies to pure titanium grades 1-4 as well as alloyed grade 5 and 23 titanium. The spec refers to requirements for hot or cold worked bars from which bolts and threaded rod are made. Titanium bolts per ASTM B348 will have special chemical composition and mechanical requirements. To comply with ASTM B348 the material is subject to chemical analyses, tensile tests, and other flexural tests and fracture toughness tests may also apply. ASTM B348 titanium bolts are required by engineers that have strict material standards for aerospace and chemical processing
