Valve material instruction:

Titanium or Titanium alloy series

Titanium (Gr.2,Gr.3,Gr.5,Gr.7,Gr.12)

ASTM B367 - Titanium Grades C-2, C-3 & C-5

Titanium (ASTM B367) 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 (No22) 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 R52550. Unalloyed titanium,

Grade C-3—UNS R52550. Unalloyed titanium,

Grade C-5—UNS R56400. Titanium alloy (6 % aluminium, 4 % vanadium),

Grade C-7—UNS R52700. Unalloyed titanium plus 0.12 to 0.25 % palladium,

Grade C-8—UNS R52700. Unalloyed titanium plus 0.12 to 0.25 % palladium,

Grade C-9—UNS R56320. Titanium alloy (3 % aluminium, 2.5 % vanadium),

Grade C-12—UNS R53400. Titanium alloy (0.3 % molybdenum, 0.8 % nickel),

Grade C-16—UNS R52402. Unalloyed titanium plus 0.04 to 0.08 % palladium,

Grade C-17—UNS R52252. Unalloyed titanium plus 0.04 to 0.08 % palladium,

Grade C-38—UNS R54250. Titanium alloy (4 % aluminium, 2.5 % vanadium, 1.5 % iron).
