600 alloy material: Excellent performance, wide range of applications!

600 nickel-based alloy plates are widely used in chemical food processing equipment, paper mills, heat exchangers and hot muffler digesters.

The alloy plates have excellent resistance to low and high temperatures and can be used in temperatures as low as 2,000 degrees Fahrenheit (1,093 degrees Celsius). In addition, it is not magnetic and easy to weld. This alloy plate is primarily used for corrosion resistance applications. Due to its high nickel content, the alloy plate has strong corrosion resistance and shows good resistance to chloride stress corrosion fracture. The presence of chromium makes it suitable for low oxidation environments.

In addition to corrosion resistance, 600 alloy plates have the following general characteristics:

Alloy 600 (designated N0660 by UNS) is a chrome-nickel alloy designed for environments ranging from low temperatures to 2000 degrees Fahrenheit (1093 degrees Celsius). The alloy is non-magnetic and easy to weld.

600 alloy is widely used in various corrosion resistance fields. Its high nickel content shows certain corrosion resistance in the environment of reduced corrosion degree, while the presence of chromium makes it have corrosion resistance in the environment of weak oxidation. In addition, the high nickel content in the alloy has special resistance to chloride corrosion fission.

In terms of corrosion resistance, the high nickel composition of the 600 alloy provides excellent resistance to appropriately weakened corrosion environments. The nickel composition gives the alloy a very strong resistance to chloride stress fission corrosion. Therefore, 600 alloy is often used in magnesium chloride solutions.

Similarly, the chromium component of the 600 alloy provides corrosion resistance in a weak oxidation environment. Compared with the 200 alloy, the 600 alloy is an improvement in this respect. However, in strong oxidizing solutions, such as concentrated hot nitric acid environment, alloy 600 has poor corrosion resistance.

Alloy 600 is relatively resistant to most neutral and saline-alkali solutions, so it is widely used in some corrosive environments.

Alloy 600 is resistant to steam and mixtures of steam, air and carbon dioxide. Its antioxidant capacity can reach high temperatures of 2100 degrees Fahrenheit (1149 degrees Celsius). However, the nickel composition makes the alloy vulnerable to erosion in sulfur-containing atmospheres at elevated temperatures.

In addition, 600 alloy also shows good cold forming characteristics, which is related to the nickel chromium stainless steel contained in it. Its high nickel content prevents the transition from austenitic steel to martensitic steel, which occurs when 301 stainless steel alloys and 304 stainless steel alloys are cold-formed. Compared with 301 alloy and 304 alloy, 600 alloy has a lower effective hardening rate and can be rolled by a variety of methods, but a lot of deformation will occur between annealing and annealing.

If high temperature annealing is used to produce relatively large particles to obtain the properties brought about by temperature rise, the maximum range of forming will cause the surface to form a clear ripple, a phenomenon known as "orange peel", which is generally considered to be harmful to material properties.

Finally, the 600 alloy can be welded using standard resistance welding and fusion welding methods for stainless steel. Electrodes and wires for welding 600 alloys and other materials can be found on the market. Because the alloy will produce strong adhesion oxides, inert gas protection measures should be used rationally.
