Annealing, quenching and heat treatment stainless steel
The operation to heating, exposure and cooling of the steel have a decisive influence on its structure. After such processing, the chemical composition remains the same, however, stainless steel is dramatically changing its properties. Ezuprechnaya distinguish hardening and heat treatment. The reduction of strength of stainless steel is necessary when the workpiece to be cut.
Deep uniform heating transformerait structure. Heat is produced directly, gradually or stepped. The heating time depends on the method (furnace, fiery or electric high frequency), by weight of the metal and the physical properties grade of stainless steel (heat capacity, thermal conductivity). The heating rate depends on the type of workpiece steel chemical composition and temperature range.
The achieved temperature ensures the completion of structural transformations. It is important to calculate the optimum time, otherwise the steel is freed from carbon and formed scale. At high temperatures the warmup time of exposure should be minimal.
Cooling water exceeds 300 °C per second, and with the furnace only 20−30°C per hour. Air cooling is faster than in the oven. These processes increase the hardness, strength, wear resistance or improving the machinability of the material.
