Characteristic as below:
Alloy c-276 is a nickel-chromium-molybdenum alloy containing tungsten and extremely low carbon and
silicon contents.
Alloy c-276 is characterised by:
1.excellent resistance to a wide range of corrosive media,under oxidizing and reducing conditions
2.excellent resistance to pitting, crevice corrosion,
Corrosion resistance:
Alloy c-276 can be used in many chemical processes with oxidizing and with reducing media.Its corrosion resistance in lightly aerated, technical grade sulphuric acid is shown in Fig. 2. Except for areas where acorrosion rate of > 0.5 mm/a is indicated the use of Alloy c-276 is considered suitable.The high molybdenum and chromium contents render the alloy resistant to chloride ion attack. The tungsten content further increases this resistance.
Alloy c-276 is one of the few materials that is resistant to moist chlorine gas, hypochlorite and chlorine
dioxide solutions. The alloy exhibits excellent resistance to concentrated solutions of oxidizing salts(such as iron (III) chloride and copper chloride)
Application range and field:
1.Pulp and paper industry, e.g. for digestion and bleaching vessels
2.Scrubbers and special reheaters as well as wet-operating
3.fans for combustion and flue gas desulphurisation systems
4.Equipment and components for sour-gas service
5.Reactors for acetic acid production
6.Sulphuric acid coolers
7.Methylene diphenyl isocyanate (MDI)
8.Manufacture and processing of technically impure phosphoric acid
9.Combustion-resistant alloy for high pressure oxygen
There are a lot of style for reference
