TIPS
What is cast steel component?
Steel castings refer to parts made of cast steel. The performance of cast steel parts is similar to that of cast iron, but stronger than cast iron. Steel castings are prone to defects such as porosity and inaccurate angle positioning during the casting process. And the shell may break during long-term use.
Advantages of cast steel parts
1. Greater design flexibility
This design has the greatest degree of freedom in selecting the shape and size of castings, especially for complex hollow parts. Steel castings can be manufactured through the unique process of core casting. Easy to form and deform, the finished product can be quickly produced according to the drawings. In this way, we can provide quick response and shorten delivery time.
2. The strongest flexibility and variability in metallurgical manufacturing
You can choose different chemical compositions and organizational structures to meet the needs of different projects. Mechanical properties can be selected through different heat treatment processes and can be used in a wide range of applications. At the same time, both weldability and usability have been improved.
3. Improve overall structural strength
Due to the high reliability of the project, coupled with weight reduction design and shorter delivery time, it can increase the competitive advantage in terms of price and economy.
4. Wide range of weight variation
Small steel castings may weigh only 10 grams, while large steel castings can weigh several tons, tens of tons, or even hundreds of tons.
shortcoming
(1) Uneven organization.
(2) The organization is not dense.
(3) Surface roughness.
(4) High cost and time-consuming.
Common defects
Common process defects include porosity, inclusions, shrinkage, porosity, and cracks.
The main defects of cast steel parts are fatigue cracks, including mechanical fatigue cracks and thermal fatigue cracks.
