Although 2205 duplex stainless steel plate can be machined, the high strength of duplex stainless steel makes machining difficult. For example, 2205 processes about 20% slower than 304.
1. Choose the appropriate processing method: you can choose drilling, milling, turning, cutting, and other methods. However, it should be noted that the hardness of duplex steel 2205 plate is relatively high, so it is necessary to use appropriate cutting tools, such as high-speed tungsten steel cutting tools, and at the same time, attention should be paid to controlling the temperature during processing.
2. Inspect the tool: Periodically check the tool for wear, blunt edges can cause excessive work hardening. Replace severely worn tools in time to ensure processing efficiency and quality.
3. Pre-processing: Before machining, 2205 stainless steel plate needs to be pre-treated, such as surface treatment, deburring, rust removal, etc., to ensure processing accuracy and surface quality.
4. Machining lubrication: Appropriate coolant or cutting oil needs to be used during machining to reduce friction and heat, protect tools and workpieces, and improve machining efficiency and quality.
5. Processing parameter setting: According to different processing methods and workpiece sizes, set corresponding processing parameters, such as speed, feed rate, cutting depth, etc., to ensure processing efficiency and quality.
