The grade 2 titanium round rod is unpolished, meets American Society for Testing and Materials International ASTM B348 and American Society of Mechanical Engineers ASME SB-348 specifications, and has a standard tolerance. The grade 2 titanium alloy is made from 98.9% titanium, is stronger than grade 1 titanium, and offers a balance of weldability, formability, and corrosion resistance.Titanium is a corrosion-resistant material that has one of the highest strength-to-weight ratios of all metals. It can be alloyed with elements such as aluminum, vanadium, iron, and molybdenum to increase properties such as strength, corrosion resistance, and toughness.Tensile strength, used to indicate the material's overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped.
