A series of experiments were conducted to validate1The experimental results show that the material has good corrosion resistance and mechanical properties.
Casting and forging are two different metal processing methods, casting is pouring molten metal into a mold and forming it after cooling; Forging is the process of putting a metal blank into a mold and beating it repeatedly to shape it. 1.The smelting process of 4122 includes electric furnace steelmaking and electroslag steelmaking, etc., which require strict control of chemical composition and impurity content to ensure product quality.
Cold rolling refers to the process of rolling a metal blank at room temperature to make it thinner and wider; Hot rolling is the process of rolling metal blanks at high temperatures to make them form; Cold drawing is the process of mechanical drawing, so that the wire is continuously reduced in diameter and obtained to the required size and shape. For 1The cold-rolled, hot-rolled and cold-drawn of 4122 needs to be operated according to the specific requirements of the product.
To sum up,14122 is a stainless steel with excellent corrosion resistance and good mechanical properties, with good machinability and weldability. Care needs to be taken to prevent corrosion problems during the application, and the quality and performance of the product can be improved through processes such as cold rolling, hot rolling and cold drawing. At the same time, the smelting process and impurity content need to be strictly controlled to ensure product quality.
