A grade is a way of classifying metals. A metal grade is designated by numbers, letters, or a combination of both. A metal grade is usually determined by its chemical composition, its mechanical properties, or both. There are many different organizations that create various standards for a given metal grade.

This grade is least used of the commercially pure titanium grades, but that does not make it any less valuable. Grade 3 is stronger than Grades 1 and 2, similar in ductility and only slightly less formable - but it possesses higher mechanicals than its predecessors.. Grade 3 is used in applications requiring moderate strength and major corrosion resistance.
