Alloy Basic Info
Description
Alloy steel is a type of steel that improves its performance by adding other alloying elements to ordinary carbon steel. These alloying elements typically include chromium, nickel, molybdenum, vanadium, etc. Alloy steel can have various performance characteristics depending on the type and content of its alloying elements, such as high strength, wear resistance, corrosion resistance, etc. Alloy steel is commonly used in the manufacturing of engineering structures, automotive parts, aerospace components, tools, bearings, etc., to meet the requirements for higher material strength, hardness, wear resistance, etc.
Hastelloy
Hastelloy is a highly corrosion-resistant alloy steel, typically containing elements such as nickel, chromium, molybdenum, etc., used in applications requiring strong corrosion resistance and high temperatures, such as chemical, petroleum, nuclear energy, etc.
Inconel
Inconel steel is a high-temperature and corrosion-resistant alloy steel, often containing elements such as nickel, chromium, etc., with excellent oxidation resistance and creep resistance, used in aerospace, chemical, nuclear energy, and other high-temperature, high-pressure fields.
Monel
Monel steel is an alloy steel containing elements such as nickel, copper, etc., with good corrosion resistance and high-temperature performance, commonly used in seawater, chemical, marine engineering, and other fields.
Incoloy
Incoloy steel is a high-temperature and corrosion-resistant alloy steel, typically containing elements such as nickel, chromium, etc., suitable for applications under high-temperature and high-pressure conditions, such as refining, chemical, power, and other industries.
