Advantages of steel castings
Steel castings refer to parts made of cast steel, which have similar properties to cast iron but better strength than cast iron. Steel castings are prone to defects such as porosity defects and inaccurate angular positioning during the casting process, and the casing may break during long-term use.
One of the advantages of steel castings is the flexibility of design. Designers have the greatest freedom of design choices for the shape and size of castings, especially for parts with complex shapes and hollow sections. Steel castings can be manufactured using the unique process of core assembly. Its formation and shape change are very easy, and the conversion speed from drawings to finished products is very fast, which is conducive to rapid quotation response and shortened delivery time. The perfect design of shape and quality, the minimum stress concentration factor, and the strongest overall structure all reflect the flexibility and technological advantages of steel casting design:
1) The metallurgical manufacturing of steel castings has strong adaptability and variability, and different chemical compositions and organizational controls can be selected to meet the requirements of various projects; Different heat treatment processes can be used to select mechanical properties and service properties over a wide range, with good welding and processing properties.
2) The isotropy of steel casting materials and the overall structural strength of steel castings improve engineering reliability. Coupled with the advantages of reduced weight design and short delivery times, it has a competitive advantage in terms of price and economy.
3) The weight of steel castings can vary over a wide range. Those with a small weight can be investment casting of only tens of grams, while large steel castings can weigh several tons, tens of tons, or even hundreds of tons
