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.

Alloy steels types

Alloy steels are classified into two types: low-alloy steels and high-alloy steels. Low-alloy steels are the most common alloy steels in investment casting.

Alloy steels Contents

Strictly speaking, all steels are alloys. but not all steel is called “alloy steels”. All steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type and content). “Alloy steel” is the standard term referring to steels with other alloying elements added also to the carbon.
The most common alloy steel material includes manganese, nickel, molybdenum, chromium, vanadium, silicon, and boron.
The Less common alloy steel material includes aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.

Alloy steels properties

Comparing with carbon steel, alloy steel has many good properties: Strength, hardness, toughness, wear resistance, corrosion resistance, and harden-ability. Our heat treatment workshop will help to improve some of these improved properties if casting can not meet them.

Main Alloys Cast and Chemical Composition

Their difference is from the content of each alloy element. please check the Alloys Cast and Chemical Composition document.

How do We Choose Casting Alloy?

Like above, There are many different types of alloys castings. Each of them has its own advantages and disadvantages. So, when we choose a casting alloy we need to consider many factors. Such as strength, durability, production volume, corrosion resistance, cost, stability, and so on.

For example, if your project requires components that are corrosion resistant with high strength. An aluminum or copper-based alloy could be an effective choice. Which alloy you use for your castings depends on which factors are required for your project.

Traditionally, alloy steel casting can get better properties than carbon steel castings. By comparison, alloy steel casting costs more for its higher material cost. Alloy steel casting is widely used for industrial applications, such as bucket teeth, agricultural wear parts, and many other industrial components that utilize cast alloy steel parts in their operations.
