The Nickel Alloy and Stainless Steel Products
Available with the Following Materials
Overview of Nickel Alloy:
Nickel based alloys refer to a type of alloy that exhibits high strength and certain oxidation and corrosion resistance at high temperatures ranging from 650 to 1000 ℃. According to their main properties, they are further 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. High temperature alloys are divided into iron based high temperature alloys, nickel based high temperature alloys, and cobalt based high temperature alloys according to their different substrates. Nickel based high-temperature alloys are abbreviated as nickel based alloys.
Alloying Elements:
The main alloying elements include chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium, etc. Among them, Cr, Ai and other elements mainly play an antioxidant role, while other elements have effects such as solid solution strengthening, precipitation strengthening, and grain boundary strengthening.
It has high strength and certain oxidation and corrosion resistance under high temperature of 650~1000 ℃. Due to its high temperature strength and corrosion resistance, it is often used to manufacture aeroengine blades and high-temperature parts on rocket engines, nuclear reactors and energy conversion equipment.
