1.Greater design flexibility
This design has the greatest freedom to choose the shape and size of castings, especially complex shapes and hollow parts, and steel castings can be manufactured by the unique process of core castings. Easy to form and change shape, and can quickly make finished products according to drawings, which can provide rapid response and shorten delivery time.
2.The strongest flexibility and variability of metallurgical manufacturing
You can choose different chemical composition and organizational structure to meet the needs of different projects. Mechanical properties can be selected by different heat treatment processes, and this property can be used in a wide range and improve weldability and usability.
3.Improve the overall structural strength
Due to the high reliability of the project, combined with the weight reduction design and short delivery time, it can improve the competitive advantage in terms of price and economy.
4.Wide range of weight changes
There are only a few hundred tons of large steel castings, and even tens of tons of small steel castings.
Steel castings compared with forged steel parts
The mechanical properties of steel castings differ little in all directions and are superior to forged steel parts. When designing some high-tech products, designers must consider the performance of materials in three directions, which highlights the advantages of castings. Regardless of weight, volume and one-time production, steel castings are easy to make complex shapes and non stress concentrated parts.
Steel castings compared with welded structures
In terms of shape and size, the flexibility of welded structure is stronger than that of forged steel parts, but compared with steel castings, it still has the following disadvantages:
1) . It is easy to deform during welding.
2) . It is difficult to form a streamlined structure.
3) . High internal stress during welding.
4) . Welds affect the appearance and reliability of components.
Steel castings are compared with iron castings and other alloy castings
Steel castings can be used in a variety of working conditions, and the mechanical properties are better than other alloy castings.
When we need parts with high tensile strength or dynamic load, important pressure vessel castings and core parts bearing heavy load at low or high temperature, in principle, we should give priority to steel castings.
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.
