Mixed acid and alkali corrosion is a common form of corrosion, which mainly refers to the corrosion reaction of metal materials in a solution containing both acidic and alkaline components. When selecting materials that are resistant to mixed acid and alkali corrosion, factors such as the material’s corrosion resistance, mechanical strength, temperature and pressure need to be taken into consideration. This article will introduce in detail the material selection for resistance to mixed acid and alkali corrosion, and introduce the application of nickel-based alloys, Hastelloys and high-temperature alloys produced by ANTON METAL in resistance to mixed acid and alkali corrosion.
Ⅰ. Material selection resistant to mixed acid and alkali corrosion
1. Titanium alloy
Titanium alloy has good corrosion resistance and mechanical properties, and is suitable for manufacturing equipment resistant to mixed acid and alkali corrosion. Among them, Ti-6Al-4V titanium alloy is a commonly used material that is resistant to mixed acid and alkali corrosion.
2. Nickel-based alloy
Nickel-based alloys have good corrosion resistance and high-temperature strength, and are suitable for manufacturing equipment resistant to mixed acid and alkali corrosion. Among them, Inconel 625 and Inconel 718 nickel-based alloys are commonly used materials that are resistant to mixed acid and alkali corrosion.
3. Hastelloy
Hastelloy is a nickel-based alloy containing high amounts of molybdenum, chromium, iron and other elements. It has good corrosion resistance and mechanical properties and is suitable for manufacturing equipment that is resistant to mixed acid and alkali corrosion. Among them, Hastelloy C-276 and Hastelloy C-22 are commonly used Hastelloy materials that are resistant to mixed acid and alkali corrosion.
4. Stainless steel
Stainless steel is an alloy containing high amounts of chromium, nickel and other elements. It has good corrosion resistance and mechanical properties and is suitable for manufacturing equipment that is resistant to mixed acid and alkali corrosion. Among them, 316L stainless steel is a commonly used material that is resistant to mixed acid and alkali corrosion.
Ⅱ. Application of nickel-based alloys, Hastelloys, high-temperature alloys and corrosion-resistant alloys produced by ANTON METAL in resistance to mixed acid and alkali corrosion
1. Nickel-based alloy
The nickel-based alloy produced by ANTON METAL has excellent corrosion resistance and high-temperature strength, and is suitable for manufacturing equipment resistant to mixed acid and alkali corrosion. For example, Inconel 625 nickel-based alloy has good corrosion resistance in both acidic and alkaline environments, and can maintain stable performance under high temperatures and pressures.
2. Hastelloy
Hastelloy alloy produced by ANTON METAL has good corrosion resistance and high temperature strength, and is suitable for manufacturing equipment resistant to mixed acid and alkali corrosion. For example, Hastelloy C-276 and Hastelloy C-22 have excellent corrosion resistance in solutions containing both acidic and alkaline components, and are widely used in equipment manufacturing in chemical, petroleum, pharmaceutical and other industries.
3. High temperature alloys
The high-temperature alloys produced by ANTON METAL have excellent high-temperature strength and corrosion resistance, and are suitable for equipment manufacturing in high-temperature, high-pressure, and highly corrosive environments. For example, Inconel 718 high-temperature alloy can still maintain good mechanical properties and corrosion resistance under high temperature and pressure, and is widely used in equipment manufacturing in aviation, aerospace, energy and other fields.
4. Corrosion-resistant alloy
The corrosion-resistant alloy produced by ANTON METAL has good corrosion resistance and mechanical properties, and is suitable for equipment manufacturing in strong corrosive media such as seawater, acid, and alkali. For example, Monel 400 corrosion-resistant alloy has good corrosion resistance in seawater and is widely used in equipment manufacturing in marine engineering, chemical industry and other fields.
