General attributes

Alloy 330 (UNS N08330) is a nickel-ferrium-chromium austenitic alloy designed for oxidation resistance and carburization at high temperatures。The nickel content of 34%-37% gives the material high resistance to chloride stress corrosion cracking and sigma phase precipitation embrittlement。 Alloy 330 contains high levels of nickel and chromium, which give the material excellent oxidation and carbonization resistance。In addition, the material also contains a certain amount of silicon, which can strengthen the oxidation resistance。The properties of the alloy show good performance under cyclic conditions of heat and cold, alternating carbonization and oxidation。

Alloy 330 has very strong corrosion resistance, especially to oxidation, carbonization and nitriding environments。The material is processed through standard machining procedures of stainless steel and nickel alloy。Widely used in the combination of cyclic heating and carburizing environment corrosion resistance。

Corrosion resistance

Alloy 330 has excellent corrosion resistance, especially to oxidation, carburizing and nitriding environments。In the water environment, the chromium component of 330 can resist the corrosion of oxidation environment, and the nickel component can enhance the corrosion resistance of reduction。The high nickel content of the alloy makes the material highly resistant to chloride stress corrosion cracking and Sigma phase embrittlement。

The oxidation resistance

Alloy 330 has excellent oxidation resistance and scaling resistance at temperatures up to 2000°F (1095°C)。Any oxide scale forms and adheres to the surface of the material, especially under alternating hot and cold cycles。

The carburizing resistance

35% nickel and a certain amount of silicon make the material have excellent carburizing resistance。In the alternating environment of carburization and oxidation, alloy 330 shows excellent resistance to "green rot"。

Heat treatment

Alloy 330 is an austenitic stainless steel which cannot be hardened by heat treatment。It can only be hardened by cold working to achieve room temperature strength。For most high temperature applications, the 330 is not annealed after cold forming or welding。

If the material requires complete annealing, it should be done in the temperature range of 1870-2050°F (1020-1120°C)。Optimum creep resistance is achieved by water quenching of the material, but so is rapid cooling to below 800°F (425°C)。

制造

Alloy 330 can be hot-formed or cold-formed using standard procedures for austenitic stainless steel and nickel alloys。The work hardening rate of the alloy can be compared with other austenitic stainless steels。

It is recommended to process the material at room temperature。If the material requires hot work, heat the material evenly to 2050-2150°F (1120-1180°C), then reduce to 1750¼°F (950°C) and cool the material quickly with water quenching。We recommend annealing after hot processing to ensure the best corrosion resistance and grain structure of the material。

The material cannot be forged or bent in the 1200-1600°F (650-870°C) range because of the low ductility of the material at this temperature range, resulting in the fracture of the intergranular structure of the austenitic alloy material。

焊接

Alloy 330 can be welded by tungsten arc, electrode welding and plasma arc processing. The corrosion resistance obtained by tungsten arc welding is the best。

Prior to welding, the material shall be annealed and kept clean and free of dirt, grease and other impurities。Grind within one inch of each side of the joint。

The temperature between the welding layers must not exceed 300°F (150°C). No heat treatment is required before or after welding。Alloy 330 can be welded into different types of metals。
