What are the requirements for sheet metal shell processing materials?

　　The requirements for sheet metal shell processing materials are as follows:

　　1. Good weldability:

　　Many sheet metal shells are welded together by spot welding, oxygen welding, arc welding or gas shielded welding, so sheet metal shell processing materials must have good welding performance.

　　2. Good cold plasticity:

　　It must have the ability to produce permanent deformation without being destroyed under the action of external force. For cold-working parts, sheet metal shell processing materials must have good cold plasticity, such as automobile parts stamping parts. For hot-working parts, they must have good hot plasticity, such as hot forging spring steel plates, hot riveted rivets, etc.

　　3. Good chemical stability:

　　Some sheet metal shells mostly work in open-air environments, often in contact with water and steam, and often work at high temperatures and corrosive gases. This requires that sheet metal shell processing materials must have good chemical stability, which requires corrosion resistance and strong rust resistance at room temperature, and no corrosion or deformation under high temperature or sun exposure.

　　4. Good dimensional accuracy and intrinsic quality of sheet metal:

　　The dimensional accuracy and intrinsic quality of sheet metal shell processing materials have a great impact on sheet metal processing, especially on molded parts. Therefore, the materials for sheet metal shell processing should focus on selecting materials with good dimensional accuracy and intrinsic quality of the sheet metal, so that the sheet metal shell processing products can better meet the needs of users.

　　To sum up, these are some requirements for sheet metal shell processing materials. Sheet metal processing is closely related to our lives. Almost all manufacturing industries are inseparable from sheet metal processing. As long as the sheet metal shell processing products that meet these material requirements can better meet the needs of various sheet metal processing, thus producing high-quality sheet metal shell processing products.
