301 is a special stainless steel material with very high hardness. If the surface treatment of the product is not carried out, it is difficult to do heat treatment. Below, Kehua Induction Heating Equipment manufacturer will tell you about the method of heat treatment of 301 stainless steel, I hope it can help you! Under the condition of complete austenite structure. Among stainless steels, 301 is the steel that is most easily strengthened by cold deformation. Through cold deformation processing, the strength and hardness of the steel can be improved, and sufficient plasticity and toughness can be retained. In addition, this steel has good rust resistance under atmospheric conditions. However, it has poor corrosion resistance in reducing media and poor corrosion resistance in chemical media such as acid, alkali and salt, so it is not recommended for harsh environments. 301 is mainly used for equipment parts that bear higher loads in the cold working state, but also hope to reduce the weight of the equipment and not rust. In addition, this steel is prone to work hardening when it is impacted by external forces, which can absorb more impact energy and provide more reliable safety protection for equipment and personnel. 2. Heat treatment of 301 stainless steel 301 is austenitic stainless steel. If surface treatment is not carried out, it is difficult to achieve this hardness in normal application state. If this is necessary, consider aging at 600°C for 2-4h and try it. 3. Material characteristics of 301 stainless steel 1. Ferritic stainless steel: It has high Cr content, good corrosion resistance and high temperature oxidation resistance. 2. Austenitic stainless steel: typical grades such as 1Cr18Ni9, 1Cr18Ni9T1 are non-magnetic, have good corrosion resistance, good temperature strength and high temperature oxidation resistance, good plasticity, good impact toughness, no notch effect, and excellent welding performance, so they are widely used. This kind of steel generally has low strength, low yield strength, and cannot be strengthened by heat treatment, but after cold pressing and processing, the tensile strength can be high and its elasticity can be improved, but the strength obtained by cold drawing at high temperature is easy. Not suitable for high loads. 3. Martensitic stainless steel: typical such as 2Cr13, GX-8, with magnetic properties, excellent shock absorption, good thermal conductivity, high strength and yield limit, and good comprehensive mechanical properties after heat treatment and strengthening. If the carbon content is high, it needs to be reprocessed after welding to eliminate stress, and it is easy to form 8-tensite after high temperature cooling. Therefore, it should be cooled slowly after forging, and should be tempered immediately. Mainly used for carrying parts. 301 stainless steel heat treatment annealing The material properties of 301 stainless steel are very hard and have strong oxidation resistance. If you have any questions about the above 301 stainless steel heat treatment method, you can go to the Guangzhou Youzao platform and find a professional for consultation.
