In addition to iron, carbon and a small amount of unavoidable silicon, manganese, phosphorus and sulfur elements, steel also contains a certain amount of alloying elements. Alloying elements in steel include one or more of silicon, manganese, molybdenum, nickel, alum, titanium, niobium, boron, lead, rare earth, etc. This kind of steel is called special alloy steel. Nickel-based alloy is a special alloy steel. This page mainly introduces the basic information of three kinds of inconel sheets including Inconel 600,Inconel 276 and Inconel 625.

Applications:
- Inconel 600 plate is resistant to high temperature oxide medium corrosion, stress corrosion and alkali corrosion. Inconel 600 plate is suitable for heat treatment and chemical processing industrial installations, nuclear power and automotive engineering.
- n10276 nickel plate is resistant to oxidative chloride aqueous solution and wet oxygen-hypochlorite corrosion. The n10276 nickel plate is suitable for welding components in strong corrosive oxidation-reduction composite media and high-temperature seawater, nuclear power main pump motor shielding sleeves, and flue gas desulfurization equipment.
- Inconel 625 plate is resistant to redox composite media, seawater corrosion, crevice corrosion, high thermal strength, and high temperature oxidation resistance. Inconel 625 plate is used in industrial applications such as aerospace engineering, gas turbines, chemical processing, oil and gas extraction, pollution control, marine and nuclear engineering.
