What is Alloy Steel?
Alloy steel refers to an iron-carbon alloy that is formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel to improve the properties of the steel. Simply put, alloy steel is a type of steel alloyed with multiple elements. JC Casting is a leading manufacturer of various forms of cast alloy steel. We can produce alloy steel castings with higher strength and corrosion resistance.
The following are common alloying elements and their functions in alloy steel:
| Alloying Elements | Main Function |
| Si | Improve the strength, hardness and wear resistance of steel. |
| Mn | Improve the strength and hardenability of steel. Improve the hot working performance of steel. |
| Cr | Improve the corrosion resistance, wear resistance and hardenability of steel. |
| Ni | Improve the toughness, corrosion resistance and low temperature performance of steel, and increase the strength and hardenability of steel. |
| Mo | Improve the strength, hardness and wear resistance of steel. Improve the corrosion resistance and high temperature strength of steel. |
| W | Improves the hardness and wear resistance of steel. It is one of the main alloying elements of high-speed steel. |
| V | Improve the strength, hardness and wear resistance of steel. Improve the toughness of steel. |
| Ti | Refine grains. Improve steel toughness and welding performance. Prevent intergranular corrosion. |
Alloy steel characteristics
There are many types of alloy steels with different properties. Which can meet the requirements of use in different fields and working conditions.
Features
- Excellent mechanical properties: By adding various alloying elements. Its strength, hardness, toughness and wear resistance can be significantly improved. For example, Mn can improve the strength and hardenability of steel. Ni can improve the toughness and corrosion resistance of steel.
- Good hardenability: Many alloy steels have excellent hardenability. Uniform mechanical properties can be obtained within a large cross-section range. Very suitable for manufacturing large mechanical parts.
- Outstanding special properties: Different alloying elements will give alloy steels different properties. For example, adding Cr and Ni to stainless steel will give it excellent corrosion resistance. Adding elements such as W and Mo to heat-resistant steel can keep good mechanical properties at high temperatures.
- Diverse processing properties: According to different alloy compositions and uses. Alloy steels can have good forging, welding, cutting and other properties.
Compared to carbon steel. Alloy steel has enhanced properties through alloying design. Making it more suitable for demanding applications.
- Strength: Enhanced mechanical strength. Suitable for load-bearing applications.
- Hardness: Improved surface hardness and wear resistance.
- Corrosion resistance: Enhanced protection against rust and oxidation.
- Toughness: Greater resistance to impact and fracture.
| Performance Dimensions | Alloy Steel | Carbon Steel |
Strength and hardness | The strength can be greatly improved by alloying, while taking into account toughness (such as adding elements such as Ni and V). | The upper strength limit is low. Brittleness increases significantly when the carbon content exceeds 0.9%. |
Corrosion resistance | Some alloy steels (such as stainless steel) have outstanding corrosion resistance. Other types of alloy steels (such as low-alloy high-strength steel) have better corrosion resistance than carbon steel. | Poor corrosion resistance. It is easy to rust in a humid environment and has weak resistance to acid, alkali and other media. |
Special features | Special properties can be obtained through alloying:- Heat-resistant steel (tungsten and molybdenum improve high-temperature strength)- Wear-resistant steel (high carbon and high chromium form carbides)- Silicon steel (silicon enhances magnetism), etc. | No special functions (such as heat resistance, wear resistance, etc.)Single performance. |
Processing performance | Machinability varies depending on alloying elements:- Low alloy steels have weldability close to carbon steel- High alloy steels require special processes to prevent cracking | Low carbon steel has good weldability. High carbon steel has poor machinability. |

WCB | Low alloy cast steel | No special alloy | General strength.Good weldability | Valves. Pipe fittings |
WC6 | Chromium-molybdenum cast steel | Cr 1.25%Mo 0.5% | High temperature resistance. Hydrogen corrosion resistance. | Petroleum refining. High temperature pipelines |
CF8M | Austenitic stainless steel | Cr-Ni-Mo | Chloride ion corrosion resistance. | Marine engineering. Salt chemical industry |
CA6NM | Martensitic stainless steel | Cr 13%Ni 4% | High strength + corrosion resistance (fresh water/steam) | Turbines. Pump shafts |
