What is steel casting?
Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape. Steel casting is one of the casting forms that is done by pouring the molten steel into the specific mold. Items such as gears, mining machines, valve bodies, wheels are all shaped through the steel casting.
Steel is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate, which requires consideration during the mold design. Attention should be paid to the thickness of mold cavities, as thinner areas will cool quicker than thicker ones, which can create internal stress points that can lead to fracture.
According to the chemical composition, Steel castings are categorized into two general groups: carbon steels and alloy steels.
Carbon steel: Carbon steels can be grouped by their carbon content. Low carbon steel (0.2% carbon) is moderately delicate and not promptly heat-treatable. Medium carbon steel is fairly harder and agreeable to fortifying by heat treatment. High carbon steel is utilized when the most extreme hardness and wear opposition are desired.
Alloy steel: Alloy steel is arranged as either low or high combination. Low-compound cast steel (≤ 8% composite substance) has mostly the same properties as the typical carbon steel, however with higher hardenability. High-composite cast steel is intended to create a particular property, for example, erosion opposition, heat obstruction, or wear resistance.
Properties and advantages of steel casting
Cast steels carry different properties. The physical properties may change when heat or other chemicals are incorporated into the process. Alloy additions can increase both impact and wear resistance.
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.
Most steels offer a good balance of strength and ductility, which makes them extremely tough and reliable. With its strength and durability, the component produced will not be easily damaged. This also allows them to withstand significant stress and strain without fracturing. Steel can also be fairly wear-resistant.
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.
Steel is the most flexible of the auxiliary designing material, so more evaluations of steel are accessible for casting than some other alloy types. With steel casting, you can create even the most complex and unique shapes you need, despite the cost of the molds may be high according to how complex they are.
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.
Applications of steel casting
The flexibility of cast steels is perfect for any industry that requires unique and durable castings, so steel casting can be widely used in many other applications, such as industrial machining tools, locks, computer tools, eletronic parts, funitures, toy parts, automation machines, cars, constructions, power generators, railways, etc.
