The material characteristics of castings

The material characteristics of castings

1, steel is like carbon steel, are made of steel ingot smelting plant comes.

2, the steel ingot is melted again through the casting, the casting process which inevitably has defects such as change of composition, grain coarsening, easy to produce shrinkage, porosity and other casting defects, so the higher the rejection rate, mechanical performance than poor.

3, steel castings is made in accordance with the requirements of the designer's model casting, and can be made into complex shapes, there are special requirements of the parts

4, in machining, steel castings is already rough, you can go directly processed into parts.
