Steel Cast

Cast steel is a steel material manufactured through a casting process with controllable composition and properties. When the strength requirements of castings are high and cast iron cannot meet the requirements, cast steel should be used. Common cast steels include stainless steel, carbon steel, alloy steel, etc.

Steel castings are widely used to manufacture various mechanical parts, especially in situations where high load, high strength, high wear resistance and high toughness are required.

01 About Carbon Steel Casting

Carbon steel is a type of steel material, and carbon is the main element that affects the mechanical properties of carbon steel. As the carbon content increases, both the yield point and tensile strength of carbon steel increase, and the tensile strength increases more than the yield point.
In addition, as the carbon content increases, the plasticity and toughness of carbon steel decrease. Carbon steel castings are widely used in mining machinery, metallurgical machinery, rolling stock, ships, hydraulic presses, turbines and other large steel parts and other complex-shaped steel parts.

02 About Alloy Steel Casting

Alloy steel used in the cast state is also called cast alloy steel. According to its use, alloy cast steel is divided into cast alloy structural steel and special-purpose alloy cast steel. The former is low and medium alloy cast steel, mainly used to make general mechanical structural parts.
The latter are mostly high alloy cast steels, such as wear-resistant cast steel, stainless acid-resistant cast steel, heat-resistant cast steel, cast alloy tool steel, etc.

Commonly used alloy steel grades: ZG20CrMo, ZG35CrMo, ZG42CrMo, ZG50Cr1Mo, ZG40Cr1, ZG35SiMnMo, ZG35CrMnSi, ZG20MnMo, ZG35CrMnMo, ZG35MnSi, etc.

03 About Stainless Steel Casting

Stainless steel casting is a manufacturing method in which molten stainless steel is poured into a mold, allowing custom stainless steel parts to be created. Stainless steel casting has many advantages such as being able to resist environmental corrosion and is widely used in various industries.

Commonly used stainless steel grades :

(1) Heat-resistant stainless steel grades: ZG30Cr7Si2, ZG40Cr13Si2, ZG40Cr17Si2, ZG40Cr24Si2, ZG40Cr28Si2, ZGCr29Si2, ZG25Cr20Ni14Si2, ZG25Cr18Ni9Si2, ZG40Cr25Ni20Si2, ZG40Cr25Ni12Si2, ZG40Cr27Ni4Si2, etc.

(2) Corrosion-resistant stainless steel grades: ZG0Cr18Ni9, ZG1Cr18Ni9, ZG0Cr18Ni9Ti, ZG1Cr18Ni9Ti, ZG15Cr12, ZG10Cr12NiMo, etc.

(3) High-strength stainless steel grades: ZG10Cr13, ZG20Cr13, ZG10Cr17, ZG1Cr19Mo2, etc.

The Advantages Of Stainless Steel Casting

Strong Corrosion Resistance

Stainless steel castings have good corrosion resistance and can resist corrosion by chemicals such as acids and alkalis. At the same time, they are not easy to rust and oxidize, and can maintain their surface finish and appearance.

Good Mechanical Properties

Stainless steel castings have excellent mechanical properties, with good strength, toughness and hardness. It is not easy to deform and break during machining, stamping, welding and other processes, and has high precision.

Good High Temperature Resistance

Stainless steel castings have good high-temperature resistance, can work in high-temperature environments for a long time, and are not easily deformed, embrittled, and damaged. They are widely used in parts that withstand high temperatures.

Easy To Process

Stainless steel castings have excellent processing performance, low processing difficulty, and are easy to drill, mill, plan and other processes. At the same time, stainless steel castings can also be cast into a variety of shapes to meet different industrial needs.

04 About Manganese Steel Casting

Manganese steel, also known as manganese alloy steel, is a high-strength steel that is mainly used to withstand harsh working conditions such as impact, extrusion, and material wear.
Manganese steel has excellent tensile strength and hardness, as well as good plasticity and toughness. Its wear resistance is also very good, allowing it to maintain stable performance in harsh working environments.
In addition, manganese steel also has good corrosion resistance and can resist the erosion of chemicals such as acids and alkalis.

Commonly used manganese steel grades are as follows:

ZG20Mn, ZG25Mn, ZG30Mn, ZG35Mn, ZG40Mn, ZG65Mn, ZG40Mn2, ZG50Mn2, Mn13, etc.

The Advantages Of Manganese Steel Casting

Manganese steel has high strength, wear resistance and corrosion resistance. These characteristics make it irreplaceable in the field of automobile manufacturing.

High strength can reduce the weight of parts and improve the overall performance of the car.

Wear resistance can extend the service life of parts and reduce maintenance costs.

Corrosion resistance can ensure that parts can still work normally in harsh environments.
