Alloy Steel Casting

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 casting, 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.
