valve material instruction
Titanium is highly resistant to chloride-containing media,
practically all salt solutions, seawater, a range of acids, organic
and inorganic chemicals and gases. The high environmental
resistance is primarily based on a very thin, tenacious and highly
protective surface oxide film. The oxide film provides high
resistance to erosion in high velocity process streams.
titanium has only half the weight of steel. It is
non-magnetic and characterized by a high melting point, high
strength-to-weight ratio and a low modulus of elasticity.
3.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).
