Description
The 20Cr13 stainless steel bell annealed coil is widely used in the manufacture of industrial products such as cutting tools, surgical instruments, springs, valves, and other applications requiring high strength, wear resistance, and certain corrosion resistance. The production process of the annealed coil includes heating, heat preservation, and slow cooling of the hard-rolled coil, covering energy consumption, material consumption, waste treatment, and environmental emissions involved in the production process. This dataset was formed by merging data from multiple sources.
Activity Description
The production process of annealed coils includes heating, heat preservation, and slow cooling of hard-rolled coils, encompassing energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
20Cr13 stainless steel bell-annealed coils are a low-carbon stainless steel product containing approximately 12%-14% chromium, offering moderate corrosion resistance and mechanical properties. The bell annealing process optimizes the internal structure of the 20Cr13 stainless steel coils, enhancing material toughness and ductility while maintaining good mechanical strength. These bell-annealed 20Cr13 stainless steel coils are widely used in the manufacturing of cutlery, surgical instruments, springs, valves, and other industrial products requiring high strength, wear resistance, and moderate corrosion resistance.

Technology comment
Bell annealing is a traditional heat treatment process in which steel coils are placed in a sealed container (i.e., bell) and heated and cooled under controlled atmosphere and temperature. This heat treatment process aims to improve the physical and mechanical properties of steel, such as increasing toughness, reducing hardness, and enhancing ductility.
