The selection of materials resistant to alkali (sodium hydroxide) corrosion is a very important issue in fields such as the chemical industry and metallurgical industry. Sodium hydroxide is a strongly alkaline substance that is corrosive to many metals and alloys. Therefore, in environments that need to resist sodium hydroxide corrosion, corrosion-resistant materials need to be selected to manufacture equipment and components to ensure their long-term stable operation. The following will introduce in detail the material selection for alkali corrosion resistance, as well as the application of nickel-based alloys, Hastelloys, high-temperature alloys, and corrosion-resistant alloys produced by ANTON METAL in alkali corrosion resistance.
1. Selection of materials resistant to alkali corrosion
1. Stainless steel: Stainless steel has good alkali resistance, and commonly used ones include AISI 304, AISI 316, etc. Stainless steel has good corrosion resistance, mechanical strength and weldability, and is suitable for low-concentration sodium hydroxide corrosive environments. However, in high concentrations of sodium hydroxide, the corrosion resistance of stainless steel will be greatly reduced.
2. Titanium alloy: Titanium alloy is a metal material with good corrosion resistance and is suitable for high-concentration sodium hydroxide corrosion environments. However, titanium alloys are more expensive and difficult to process.
3. Nickel-based alloy: Nickel-based alloy is an excellent material resistant to acid and alkali corrosion. It has good alkali corrosion resistance and is especially suitable for high-concentration sodium hydroxide corrosion environments. Nickel-based alloys have high strength, toughness and heat resistance, and are suitable for high temperatures and corrosive environments.
4. Polymer material: Polymer material is a material with good acid and alkali corrosion resistance. However, polymer materials have relatively low mechanical strength and heat resistance and are suitable for low temperature and low pressure environments.
2. Introduction to Tianjin Anton Metal Manufacture Co., Ltd. and the application of its products in alkali corrosion resistance
Tianjin Anton Metal Manufacture Co., Ltd., founded in 1989 with a registered capital of 10 million, is a company specializing in the production of various nickel-based alloys, Hastelloy and high-temperature alloy materials. Its products are widely used in aerospace, shipbuilding, chemical industry, petroleum, electric power, medical and other fields. The following are the applications of several ANTON METAL products in alkali corrosion resistance:
1. Nickel-based alloy
The nickel-based alloy produced by ANTON METAL has good corrosion resistance and high temperature resistance. Nickel-based alloy is a commonly used corrosion-resistant material in high-concentration sodium hydroxide corrosive environments. For example, Incoloy 825 nickel-based alloy produced by ANTON METAL has excellent corrosion resistance in sodium hydroxide solutions with concentrations up to 70%, and is suitable for manufacturing chemical equipment, marine equipment, etc.
2. Hastelloy
Hastelloy produced by ANTON METAL is a cobalt-based or nickel-based high-temperature alloy with good high-temperature strength and corrosion resistance. Hastelloy is an excellent corrosion-resistant material in high-temperature, high-pressure, and highly corrosive chemical environments. For example, Haynes 230 alloy produced by ANTON METAL can operate stably for a long time at high temperatures and has good corrosion resistance under strong alkaline conditions. It is suitable for manufacturing high-temperature stoves, petrochemical equipment, etc.
3. High temperature alloys
The high-temperature alloys produced by ANTON METAL have good high-temperature strength, corrosion resistance and oxidation resistance. In high-temperature, high-pressure, and highly corrosive chemical environments, high-temperature alloys are excellent corrosion-resistant materials. For example, Inconel 625 high-temperature alloy produced by ANTON METAL has good corrosion resistance and is suitable for manufacturing aerospace engine parts, chemical equipment, etc.
4. Corrosion-resistant alloy
The corrosion-resistant alloy produced by ANTON METAL is an alloy material with good corrosion resistance. In corrosive environments, corrosion-resistant alloys can operate stably for a long time and have good mechanical properties. For example, C-276 corrosion-resistant alloy produced by ANTON METAL is a nickel-based alloy with good corrosion resistance and is suitable for manufacturing chemical equipment, marine equipment, etc.
In general, the nickel-based alloys, Hastelloys, high-temperature alloys, corrosion-resistant alloys and other materials produced by ANTON METAL have excellent performance in resisting alkali (sodium hydroxide) corrosion and are suitable for manufacturing chemical equipment, marine equipment, petroleum equipment Chemical equipment, etc.
Tianjin Anton Metal Manufacture Co., Ltd. is a company specializing in the production of various nickel-based alloys, Hastelloy alloys and high-temperature alloy materials.
