Nickel and nickel alloys have better corrosion resistance than stainless steel in strongly corrosive media, and have better high-temperature oxidation resistance and high-temperature strength than heat-resistant steel. Pure nickel has good corrosion resistance in oxidizing media, often has the same open circuit potential as platinum in reducing acid system, has excellent corrosion resistance in hot concentrated lye, and does not produce alkali brittle stress corrosion, Pure nickel has excellent corrosion resistance to hydrochloric acid, but it is expensive and is generally only used on the side in contact with the corrosive medium. The strength and stiffness are borne by carbon steel and low alloy steel, thus manufacturing nickel-steel clad plates.
Nickel has excellent corrosion resistance in highly concentrated alkali and reducing mediums, which is unmatched by other metal materials. In recent years, with the rapid development of the economy, the excellent corrosion resistance of nickel materials has attracted more and more people's attention Attention, the scope of application is also expanding, but the proportion of nickel is large and the price is high. Considering its economy in the design, it is often used as a lining or bimetal cladding, so the nickel-steel clad plate is the common material for the above-mentioned medium. The performance of nickel and the Welding between nickel steels is different from other materials.
Metal clad plates are widely used in petrochemical equipment because they have sufficient strength, can well meet the requirements of corrosion resistance, and are relatively economical. Pure nickel is a single-phase austenite structure with excellent corrosion resistance, good mechanical properties, high heat resistance, and special electromagnetic and thermal expansion properties, so nickel is a good material for manufacturing chemical equipment, but due to pure nickel is Expensive and its application is limited.
