The surface heat treatment of Corten steel can improve the processing properties of the steel, improve its properties, significantly improve the mechanical properties of the steel, and prolong its service life. The quality of surface heat treatment of flame surface quenching is affected by the following factors:
1. The relative speed between the nozzle and the Corten steel: adjust the thickness and relative speed of the hardened layer according to the requirements of the workpiece. If the tandy is deep, the speed will slow down, if the hardened layer is thin, the speed will be fast.
2. The distance between the nozzle and the flame: the distance between the nozzle and the flame should be kept at about 1 mm, too far or too close will affect the quenching quality of Corten steel.
3. Cooling water temperature, the water temperature should not be too low to avoid cracks: Corten steel should be tempered in time, and the tempering temperature is about 180℃.
When purchasing Corten steel, it is necessary to specify the specific thickness, as well as the delivery status of Corten steel, which is divided into casting and rolling. The casting is very rough, the density is low, and the price is low. Therefore, it is generally necessary to ask clearly about the choice of rolling and solution delivery status. In terms of price, it is recommended to consider carefully the Corten steel whose price is too low.
