Due to the particularity of stainless steel plate, its main processing methods include cold processing and hot processing. However, cold processing is often slow and inefficient, mainly used for cutting specifications and shapes. There are many hot working methods. According to different situations, the cutting effect is different, and the cost is also different. For details, we can see the specific cutting method.
1. Flame cutting equipment: low cost, it is a means of cutting thick metal plates, but it has its disadvantages when cutting thin plates. Compared with plasma, flame cutting has larger heat affected zone and larger thermal deformation.
2. Laser cutting: The laser cutting equipment can cut stainless steel plates less than 30 mm, and 40 mm thick carbon steel can be cut by adding oxygen to the laser beam, but a thin oxide film will be formed on the cutting surface after cutting with oxygen.
3. Wire cutting: wire cutting is referred to as electric spark wire. It is developed on the basis of electric spark drilling. It not only develops the application of EDM, but also replaces EDM drilling in some aspects.
4. Plate shears: The plate shears exert shear force on stainless steel plates of various thicknesses through moving upper blades and fixed lower blades, so that the metal plates can be broken and separated according to the required size. Shearing machine is one of the forging machines, mainly used in metal processing industry.
5. Plasma cutting machine: plasma cutting is a processing method that uses the heat of high temperature plasma arc to melt (and evaporate) the stainless steel plate part or workpiece gap part, and uses the momentum of high-speed plasma to remove molten metal to form a gap.
The cold processing methods of stainless steel plate cutting mainly include sawing machine cutting, wire cutting, water cutting, plate cutting, punch machining, drilling and other methods. The molding quality is generally high, but the efficiency is low. It is often

Stainless steel has excellent comprehensive properties, appearance and surface properties, and is widely used in all stages. Similarly, stainless steel pipe is no exception. Stainless steel pipe is a kind of hollow section steel, which is generally divided into stainless steel seamless pipe and welded pipe. There are some differences in processing methods and performance. The difference is:
1. Differences in the production process
After rolling the steel plate or strip, the stainless steel welded pipe is welded to form the equipment and mold. The inner wall of the tube usually has welds. Seamless tubes are made of round tube blanks and drilled, cold rolled and cold drawn through the hot extrusion production process. There are no welding points in the tube.
2. Appearance difference of steel pipe
For stainless steel welded pipe, the wall thickness tolerance is very small, and the thickness of the entire circumference is very uniform. The steel pipe has high precision, high brightness of internal and external surfaces, and the length can be set arbitrarily. Seamless steel pipe has low precision, uneven wall thickness, low brightness of internal and external surfaces, high cost of fixed size, internal and external installation and black spots. Therefore, the seamless pipe wall is usually thicker.
3. Difference between performance and price
Seamless pipe has higher corrosion resistance, pressure resistance and high temperature resistance than welded pipe. With the improvement of the manufacturing process of welded pipe, the mechanical properties and mechanical properties are gradually approaching seamless pipe. Seamless tubes are more complex in the manufacturing process and more expensive than welded tubes.
According to the characteristics and differences between stainless steel seamless pipe and welded pipe, reasonable selection and application are required to achieve economic, beautiful and reliable effects.
