Dongguan Precision CastingThe advantages of steel castings:

1. Greater design flexibility

This design is free to choose the shape and size of castings, especially complex shapes and hollow parts. Steel castings can be manufactured with unique core casting technology. It is easy to deform after molding, and it can be quickly formed according to the drawings, which can be quickly responded and the delivery time is short.

Metallurgical processing has flexibility and variability.

Different chemical compositions and organizational structures can be selected according to project needs. Various heat treatment processes can be selected to improve mechanical properties and are widely used to improve weldability and adaptability.

2. Strengthen the strength of the overall structure.

High-reliability projects, coupled with weight reduction design and short delivery time, can gain a competitive advantage in price and economy.

Fourth, the range of weight change is large.

Small steel castings can reach 10 grams, and large steel castings can reach several tons, dozens of tons, or even hundreds of tons.

3. Compared with forged steel parts:

The mechanical properties of steel castings are not much different in all directions, and are better than forged steel parts. When designing some high-tech products, designers must consider the properties of materials from three directions, so as to highlight the advantages of castings. Regardless of weight, volume and one-time production volume, steel castings are easy to produce complex shapes and non-stress-concentrated parts.

4. Compared with welded structure:

In terms of shape and size, the flexibility of the welded structure is stronger than that of forged steel parts, but compared with steel castings, it has the following disadvantages

1) Easy to deform during welding.

2) It is difficult to form a streamlined structure.

3) High internal stress during welding.

4) The weld affects the appearance and reliability of the component.

5. Compared with iron casting and other alloy castings.

Steel castings can be used in various working conditions, and the mechanical properties are better than other alloy castings.

When we need high tensile strength or dynamic load components, important pressure vessel castings and core components that bear heavy loads at low or high temperatures, steel castings should be used in principle.

However, the vibration absorption, wear resistance and mobility of steel castings are not as good as iron castings, and the cost is also higher than iron castings. Dongguan Precision Casting
