ASTM B**7 - Titanium Grades C*2, C*3 & C*5

Titanium (ASTM B**7) is very light and very strong. Whilst it is an expensive material weight for weight with many other materials, its high strength can be utilized to good effect in designs, by reducing wall thickness and subsequently weight and cost. The poor wear and galling properties of Titanium must be considered in any design. Casting and welding processes are required to be conducted by specialists.

It has exceptional corrosion resistance to many corrosive media including hydrochloric acid and wet chlorine.

WARNING! Do not use on Hydrofluoric acid and Methanol as excessive corrosion and cracking will occur.

Titanium Chemical Composition

While Titanium is an element (No*2) and is commercially pure, as a cast product it is often alloyed with small quantities of Paladium, Aluminium & Vanadium.

Common grades in regular use:

Grade C*2—UNS R****0. Unalloyed titanium,

Grade C*3—UNS R****0. Unalloyed titanium,

Grade C*5—UNS R****0. Titanium alloy (6 % aluminium, 4 % vanadium),

Grade C*7—UNS R****0. Unalloyed titanium plus 0.*2 to 0.*5 % palladium,

Grade C*8—UNS R****0. Unalloyed titanium plus 0.*2 to 0.*5 % palladium,

Grade C*9—UNS R****0. Titanium alloy (3 % aluminium, 2.5 % vanadium),

Grade C**2—UNS R****0. Titanium alloy (0.3 % molybdenum, 0.8 % nickel),

Grade C**6—UNS R****2. Unalloyed titanium plus 0.*4 to 0.*8 % palladium,

Grade C**7—UNS R****2. Unalloyed titanium plus 0.*4 to 0.*8 % palladium,

Grade C**8—UNS R****0. Titanium alloy (4 % aluminium, 2.5 % vanadium, 1.5 % iron).
