Nickel alloys refer to a class of alloys with comprehensive properties such as high strength and certain oxidation and corrosion resistance at a high temperature of 650-1000°C. Nickel alloy seamless pipes are widely used in petroleum, chemical, high-pressure boilers, nuclear power, aviation, marine engineering, environmental protection engineering and other fields.

Compared with ordinary stainless steel, nickel-based alloys have superior high-temperature resistance, corrosion resistance and high strength properties. It is suitable for strong acid-base and high-temperature environments under harsh conditions.

According to the main properties, it can be divided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys.

Nickel-based heat-resistant alloy: nickel-chromium alloy, the main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium, etc. Among them, Cr and Ai mainly play an anti-oxidation effect, and other elements have solid solution strengthening, precipitation strengthening and grain boundary strengthening.

Nickel-based corrosion-resistant alloy: The main alloying elements are copper, chromium, and molybdenum. It has good comprehensive performance and can resist various acid corrosion and stress corrosion. These nickel-based corrosion-resistant alloys are mainly used in the manufacture of various corrosion-resistant environmental parts such as petroleum, chemical industry, and electric power.

Nickel-based wear-resistant alloy: the main alloying elements are chromium, molybdenum, tungsten, and also contain a small amount of niobium, tantalum and indium. In addition, to wear resistance, its oxidation resistance, corrosion resistance, and welding performance are also good.

Nickel-based precision alloys: including nickel-based soft magnetic alloys, nickel-based precision resistance alloys and nickel-based electric heating alloys.

Nickel-based shape memory alloy: a nickel alloy containing 50 (at)% titanium. The recovery temperature is 70°C, and the shape memory effect is good. It is mostly used to manufacture self-exciting structural parts used on spacecraft and self-exciting fasteners used in the aerospace industry.
