What is Alloy Steel Casting

Alloy steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. According to the different added elements, and adopt appropriate processing technology, can obtain high strength, high toughness, wear resistance, corrosion resistance, low-temperature resistance, high-temperature resistance, non-magnetic and other special properties. Alloy steel is mainly divided into two categories: low alloy steel and high alloy steel. Investment cast alloy steels are usually low alloy steels.

Advantages of Alloy Steel Casting

Different alloys will have different properties. Common improvements include corrosion resistance, oxidation resistance and improved heat resistance. For example, molybdenum can increase material strength; nickel increases toughness; chromium can increase temperature strength, hardness and corrosion resistance.

Application of Alloy Steel Investment Casting

Alloy steel has good wear resistance and corrosion resistance, and strength performance is very high. Therefore, it can be used in the fields of engineering machinery and equipment, loading and unloading machinery, mining machinery and equipment, metallurgical machinery and equipment, construction machinery and equipment.
