Stainless Steel DIN 1.4841 Pipes
The density of 1.4841 is approximately 7.9g/cm³.
Weight calculation formula:
Weight (kg) = Width (mm) × Length (mm) × Thickness (mm) × Density (g/cm³) ÷1000
Processing and polishing:
1. During the processing and polishing of 4841 stainless steel, attention needs to be paid to the cutting speed and cutting depth. The surface can be treated through mechanical polishing, chemical polishing and other methods to improve its smoothness and aesthetics.
1.4841 heat-resistant stainless steel pipe processing process:
1. Cutting: Use mechanical cutting or plasma cutting to ensure a smooth cut and avoid excessive stress concentration.
2. Cold working: Conventional cold working methods, such as drilling, milling, turning, etc., can be used for preliminary shaping.
3. Hot processing: When forming is required, hot processing can be used, such as forging, hot rolling and other processes to ensure the plastic deformation performance of the material at high temperatures.
4. Welding: Use appropriate welding materials and welding processes to ensure the quality and heat resistance of the welded joints.
