Precision steel castings have high dimensional accuracy for casting steel, the general linear tolerance is 1%, the angle tolerance is + 1/2 degrees, and the surface finish can reach Ra 1.6 – 3.2, which saves material and machining cost. It can produce parts with complex shapes, or cast multiple parts into one, eliminating the combination or welding work. It can cast exquisite characters or logo patterns on the product surface to improve the product image. The casting materials have a wide range of properties, such as heat resistance, wear resistance, corrosion resistance, and material hardness up to hrc15-60, so as to meet the requirements of various working conditions. The production batch and quantity of castings are flexible, from small quantity to large quantity, with high efficiency and good repeatability; the mold cost is low, and the initial investment of product development is small.
Most of the large-scale precision steel castings are the main load-bearing parts and supporting parts in the major technical equipment. The size of the castings is huge, the shape is complex, and the section thickness is very different. This kind of castings are often in the high temperature and high pressure working state. The performance and quality requirements are very strict, especially the high temperature performance requirements are more strict.
All steel castings shall be used after heat treatment. The strength, especially plasticity and toughness of steel castings are greatly reduced because of the casting defects such as porosity, crack, shrinkage cavity and porosity, coarse grain, uneven structure and residual internal stress.
