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.
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.
