What is Low Alloy Steel Casting?

Alloy steel is formed by adding some appropriate amount of one or more alloying elements to ordinary carbon steel.It is an iron-carbon alloy 

Becuase of different  elements added, and adopt appropriate processing technology, the low alloy steel casting can obtain high strength, high toughness, worn-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 casting alloy steels are usually low alloy steels.

As we all know, different steel alloys will have different properties. The common improvements include corrosion resistance, oxidation resistance and improved heat resistance. For example, molybdenum can increase material strength; nickel can increase toughness; chromium can increase temperature strength, hardness and corrosion resistance.

Alloy steel has good worn-resistance and corrosion-resistance, and its strength performance is very high. so 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 etc.
