Corrosion in precision parts processing refers to the phenomenon of metal surface damage caused by chemical or electrochemical reactions between metals and media in a specific environment. In many industries, such as chemical, petroleum, and marine, corrosion is a common problem. In order to solve the corrosion problem, a series of corrosion-resistant metal materials have been developed. Below, we will introduce some commonly used corrosion-resistant metal materials.
Stainless steel: Stainless steel is a metal material mainly composed of iron, chromium, and other elements. It has excellent corrosion resistance and can maintain good stability in most corrosive media. The corrosion resistance of stainless steel mainly depends on its chromium content, which is generally above 10% in order to be called stainless steel.
Nickel alloy: Nickel alloy is a type of material mainly formed by alloying nickel and other elements. Nickel alloys have excellent corrosion resistance and can maintain good stability in corrosive media such as strong acids, alkalis, and salts. Nickel alloys are widely used in industries such as chemical and petroleum.
Titanium alloy: Titanium alloy is an alloy material mainly composed of titanium. Titanium alloys have excellent corrosion resistance and can be used stably in harsh environments such as strong acids, salts, and oxidants for a long time. Due to its lightweight characteristics, titanium alloys are widely used in fields such as aviation and aerospace.
Copper alloy: Copper alloy is a material made by alloying copper with other elements as the main component. Copper alloys have good corrosion resistance and can maintain good stability in media such as seawater and steam. Copper alloys are widely used in fields such as ocean engineering and shipbuilding.
In addition to the common corrosion-resistant metal materials mentioned above, there are also many other types of corrosion-resistant materials, such as molybdenum alloys, zirconium alloys, etc. These materials have different corrosion resistance properties in different environments, and suitable materials need to be selected based on specific usage conditions.
Corrosion resistant metal materials play an important role in solving corrosion problems in precision parts processing. By selecting appropriate corrosion-resistant materials, it is possible to effectively prevent metal corrosion in harsh environments, extend the service life of equipment, and improve production efficiency. Therefore, for industries and fields that need to be used in corrosive environments, understanding and applying corrosion-resistant metal materials is very important.
