Nickel Based Alloy Tubes Seamless Nickel Alloy Pipe  are alloys that have a combination of high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000 °C. According to the main performance, Nickel Copper Alloy Seamless Pipe  is subdivided into nickel-based heat-resistant alloy, nickel-based corrosion-resistant alloy, nickel-based wear-resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. Superalloys are classified into iron-based superalloys, nickel-based superalloys and cobalt-based superalloys according to the matrix. Among them, nickel-based superalloys are referred to as nickel-based alloys.

Ferritic Stainless Steel Pipe/Tube  Ferritic stainless steel (400 series) contains 15% to 30% chromium and has a body-centered cubic crystal structure. These steels generally do not contain nickel, and sometimes contain a small amount of elements such as Mo, Ti, Nb, etc. These steels have the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance and excellent resistance to stress corrosion. Ferritic stainless steel is mostly used to make parts resistant to atmospheric, water vapor, water and oxidative acid corrosion. Ferritic stainless steels have many unique features and advantages, and ferritic stainless steels have proven to be an excellent alternative to ferrites in many applications where austenitic stainless steels (300 series) were originally considered to be used. Stainless steel does not contain nickel, the main element is chromium (>10%) and iron, which is a particularly corrosion-resistant element of stainless steel, an

ASTM A789 Gerneral Service Stainless Steel Pipe The duplex stainless steel tube  has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel  pipe , it is not like the welding heat affected zone of ferritic stainless steel, and the plastic toughness is greatly reduced due to severe grain coarsening. Nor is it sensitive to hot cracking of welds like austenitic stainless steel. Due to its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery and other industrial fields. In recent years, it has also been studied in the field of bridge load-bearing structures. Prospects. Duplex stainless steel is half of the ferrite phase and austenite phase in its solidified structure, and the minimum phase content may be up to 30%.
