Sheet dimesion:
Thickness:0.3-20mm
Width:100-1500mm
Length:500-3000mm
Characteristics:
Excellent mechanical properties at both extremely low and extremely high temperatures.
Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.
Almost complete freedom from chloride induced stress corrosion cracking.
High resistance to oxidation at elevated temperatures up to 1050C.
Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.
Features
High creep-rupture strength
Oxidation resistant to 1800 F degree
Good fatigue resistance
Excellent weldability
Outstanding resistance to chloride pitting and crevice corrosion
Immune to chloride ion stress corrosion cracking
Resistant to seawater under both flowing and stagnant conditions and under fouling
Applications
Aircraft ducting systems
Jet engine exhaust systems
Engine thrust-reverser systems
Bellows and expansion joints
Turbine shroud rings
Flare stacks
Seawater components
Chemical process equipment handling mixed acids both oxidizing and reducing.
