Super stainless steel tube is a type of Fe-based super alloy, of which chrome content is 12～30%. Super stainless steel tube can be divided into four types according to the microstructure characteristic: super austenitic stainless steel, super ferrite stainless steel, super duplex stainless steel and super martensitic stainless steel.
In recent years, along with the good running of macroeconomic environment and development situation of industry in China, various industries are subjected to varying degrees, and nickel-based alloy is no exception.
Nickel-based alloys have high strength and relatively comprehensive resistance to oxidation and corrosion at 650~1000℃. According to performance, nickel-based alloys are divided into heat-resistant alloys, corrosion-resistant alloys, wear-resistant alloys, precision alloys and shape memory alloys.
Corrosion-resistant alloy compound pipes consist of two different metallic materials, the pipe layer close combined by various deformation and connection technology.
