1. Solution Annealing: Solution Annealing is one of the most commonly used heat treatment methods. By heating the ss304 plate to a temperature range of about 1010°C to 1120°C (1850°F to 2050°F), followed by rapid cooling, the intergranular carbides inside the material can be eliminated and its corrosion resistance and mechanical properties can be improved.
2. Cold Working: Cold working is to enhance the strength and hardness of the material by plastically deforming the 304 stainless steel plate at room temperature. Common cold treatment methods include cold rolling, cold drawing, and cold bending. Cold treatment can improve the tensile strength and hardness of 304 stainless steel plates, but it will reduce its plasticity and toughness.
3. Quenching: Quenching is to increase the hardness and strength of the 304 steel plate by rapidly cooling it. In general, s30400 stainless steel does not change its structure and properties by quenching, because it is prone to intergranular corrosion during quenching.
4. Solution Precipitation Hardening: Some special types of 304 stainless steel (such as 304H and 304N) can change their properties through solution precipitation hardening. This heat treatment method involves heating the 304 stainless steel sheet to an appropriate temperature and then performing the aging treatment in a solid solution state to increase its strength and hardness.
