Properties of Cast Steel
Cast steels carry different properties. The physical properties may change when heat or other chemicals are incorporated into the process. The cast steel will be carefully selected and processed so it will produce the needed output.
Toughness
Cast steels can endure stress. To adjust the toughness of cast steels, one may alloy metals and apply heat.
Hardness
Steel casting is abrasion-free. It has high levels of hardness that even scratches will not be seen in the material.
Strength
It is difficult to deform cast steels by force. This is how strong it is. This also determines its durability.
Wear Resistant
Cast steels are wear and tear-resistant. It can resist friction and frequent use. Its wear resistance levels make it perfect for components that will be severely used.
Rust Resistant
This allows the material to be corrosion-resistant. Despite constant use, cast steels have a high tolerance of elements that can cause corrosion.
Ability to be Welded
This is the edge of cast steels over other castings. It can be welded to create shapes and forms needed without being damaged.
Advantages of Steel Castings
Steel castings are widely used in many industries. These are also used in household and commercial products. It has become popular and in-demand because of the advantages it provides.
Reliable
Steel castings are reliable. With its strength and durability, the component produced will not easily give in to damage. It promises longevity to the industry it will serve.
Economically Beneficial
The prices of cast steels are competitive in the market as compared to other castings. You can find reasonable rates but still get the same quality and durability that you are expecting from it.
Design Flexibility
With steel castings, you can create even the most complex and unique shapes, designs, and forms you need. This is easy to form and deform if needed. The flexibility of cast steels is perfect for any industry that requires unique and durable castings.
Adaptability
Cast steels can go through any processes needed. It can adapt well to different chemical compositions, heat, and other procedures required to produce a component.
Types of Cast Steel
Cast Steel has many types. According to chemical composition, cast steels are categorized into two general groups. These are carbon cast steels and alloy cast steels.
Carbon Steels
Carbon steels are special types of steel. Because it has a higher concentration of carbon. It also has types of low carbon steel,medium-carbon steel,high-carbon steel. With this, it provides a lot more benefits to its users. Carbon steels are stronger and more durable as compared to ordinary steels. It is more resistant to stress but may still break if exposed excessively. This type of cast steel is being used in industries like construction, automotive, and many others.
Generally speaking,low carbon steel ZG15 has a higher melting point, but poor casting performance. It is only used to manufacture motor parts or carburized parts.
Medium carbon steel ZG25～ZG45 has comprehensive properties higher than all kinds of cast iron. That is a high strength, excellent plasticity, and toughness. Therefore, it is suitable for manufacturing parts with complex shapes, high strength, and toughness requirements. Such as train wheels, forging hammer stands and anvils, rolls, and high-pressure valves. It is the most widely used type of carbon cast steel.
The high carbon steel ZG55 has a low melting point. Its casting performance is better than that of medium carbon steel. But its plasticity and toughness are poor. It is only used to manufacture a few wear parts.
Alloy Steels
Alloy steels are formed when elements that are composed of metals and non-metals are joined with carbon steels. These are used in many industries such as mining, automobiles, road construction, and many more. Alloy steels are not just for big components, they are also used to make small and basic household equipment.
According to the total amount of alloying elements, alloy cast steel can be divided into two categories: low alloy steel and high alloy steel.
(1) Low alloy cast steel. my country mainly uses manganese series, manganese silicon series and chromium series. Such as ZG40Mn, ZG30MnSi1, ZG30Cr1MnSi1, etc. Used to make parts such as gears, hydraulic press working cylinders and hydraulic turbine rotors. And ZG40Cr1 is commonly used to manufacture important stressed parts such as high-strength gears and high-strength shafts.
(2) High alloy cast steel. It has special properties such as wear resistance, heat resistance or corrosion resistance. Such as high manganese steel ZGMn13. It is a kind of anti-wear steel. Mainly used to manufacture parts used under dry friction working conditions. Such as the front wall and teeth of the grab bucket of excavators, the crawler tracks of tractors and tanks, etc. Chromium-nickel stainless steel ZG1Cr18Ni9 and chromium stainless steel ZG1Cr13 and ZGCr28, etc. High corrosion resistance to nitric acid. Mainly used in the manufacture of chemical, petroleum, chemical fiber, food and other equipment parts.
In comparison, while both types of steel are useful and in demand, they are the total contrast in terms of their properties. Alloy steels are more corrosion resistant than carbon steels. But its strength and durability are inferior to carbon steel. There are many contrasting properties and elements between carbon steels and alloy steels. But in the end, both are highly useful for many industries and trades.
