What is Alloy Steel Casting
What is Alloy Steel Casting? Alloy steel casting is a steel casting process that is one kind of alloy castings. It is alloyed with numerous elements in total amounts between 1.0% and 50% by weight. The alloy casting can improve its mechanical properties. According to the different added elements and adopting appropriate processing technology, we 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 steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels have two main groups: low-alloy steels and high-alloy steels. Mostly, Investment cast alloy steels are usually low alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called “alloy steels”. The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on the type). But, the term “alloy steel” refers to steels with other alloying elements added deliberately in addition to the carbon.
Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron.
Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.
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 investment casting can produce a wide array of complex parts and precision components. By heating the material above its melting point and pouring it into the mold, it will solidify into the required shape.
Quality alloy steel casting follows seven steps: Pattern production, mold making and preparation, wax model/tree assembly, sand shell & dewaxing, material pouring, refining, and testing.
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.
