What problems will occur if the carbon content of stainless steel precision casting is too high?

Excessive carbon content in stainless steel castings may cause some problems. Typically, stainless steel obtains its corrosion resistance and oxidation resistance by controlling the carbon content at a low level. Excessive carbon content may cause the following problems:

1. Decreased corrosion performance: Excessive carbon content will reduce the corrosion resistance of stainless steel, making it more susceptible to oxidation, corrosion and rust.

2. Reduced welding performance: High carbon content will increase the hardness and brittleness of castings, making welding more difficult and may cause welding defects such as cracks and deformation.

3. Reduced mechanical properties: Excessive carbon content will reduce the toughness and strength of stainless steel, making it prone to fracture and deformation during use.

Therefore, for stainless steel castings, it is very important to control the carbon content within an appropriate range to ensure that it has good corrosion resistance and mechanical properties. The specific carbon content requirements will vary according to different stainless steel materials and application fields. According to the differences, it is recommended to follow the corresponding standards and specifications during the design and manufacturing process.
