Heat treatment of iron and steel is the key factor that affects the production efficiency and the quality of finished products. Annealing process, normalizing process, quenching process, tempering process, surface quenching process, chemical heat treatment process are several major heat treatment processes. Sodium cyanate is a kind of heat treatment agent which is widely used as quenchant in steel processing.
Sodium cyanate is often used as carburizing agent and nitriding agent in metal heat treatment. The toughness, wear resistance and corrosion resistance of metal surface treated with sodium cyanate are increased, and the fatigue life is obviously increased, especially for copper, which can be increased by 80%.
1. Steel parts with sodium cyanate have higher surface hardness and wear resistance 2. The steel parts with sodium cyanate have better thermal stability. 3. The steel using sodium cyanate has higher fatigue strength, anti seizing property and lower notch sensitivity. 4. After treatment, the surface of the steel parts forms dense corrosion resistance. 5. Different application scope. The steel parts treated with sodium cyanate are widely used in the mechanical industry, especially suitable for the final heat treatment of many precision parts, such as grinding machine spindle, boring machine boring bar, precision machine lead screw engine crankshaft and various precision gears and measuring tools.
In the process of casting, pressure processing and welding forming, there are inevitably organizational defects, such as quenching crack, deformation out of tolerance, hardness deficiency, electrical processing crack, grinding crack, early damage of mold, etc. The heat treatment of metal materials is mainly due to the improvement of their comprehensive mechanical properties. Sodium cyanate conforms to the principle of "composition organization performance" followed in the design and preparation of materials.
