The corrosion resistance of stainless steel is mainly composed of C content and precipitated carbide. Therefore, the lower the C content of corrosion-resistant stainless steel, the better, usually C≤0.08%. However, the high temperature mechanical properties of heat-resistant steel are determined by its stability in the structure. The carbide precipitation phase, so the heat-resistant steel has a high C content, generally containing more than 0.20% carbon. Classified according to metallographic organization, stainless steel is divided into ferritic stainless steel, martensitic stainless steel, austenitic stainless steel and biphasic (ferritic in austenitic matrix) stainless steel.Everyone should know that stainless steel castings are widely used in various industries. So, do you know what precautions are there when pouring? I believe that everyone is not very understanding, then let me introduce you briefly. 1. Casting speed: Under the condition that the gas in the cavity is discharge |
