Cut.
In shearing and cutting, the most commonly used method is to use a shearing machine, which is suitable for ordinary carbon steel and stainless steel. The cutters for cutting stainless steel must be made of high-speed tool steel. To obtain a smooth edge, the cutting surface of the tool must be sharp and free of burrs.
Stainless steel plates, especially austenitic stainless steel, have higher ductility, so the gap between the cutters must be reduced when cutting, and the shear must be ensured to be crisp and clear. The stainless steel must not be plastically deformed or the cutter must be pulled down. Before fracture occurs, the tool should shear to just half of the plate thickness, and the margin at this time is more appropriate. Excessive tool allowance will cause damage to the tool, and there will also be very large burrs on the edge of the cut steel plate.

Notes:
1. Stainless steel plates have a similar ability to resist general corrosion as unstable nickel-chromium alloy 304. Prolonged heating in the temperature range of chromium carbide levels may affect alloys 321 and 347 in harsh corrosive media. Mainly used for high temperature applications, which require materials with strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.
2. High-temperature oxidation resistance: Stainless steel plates all have high-temperature oxidation resistance. However, the oxidation rate will be affected by inherent factors such as the exposure environment and product form.
3. Physical properties: In addition to the thermal conductivity of the metal, the total heat transfer coefficient of the metal also depends on other factors. In most cases, the heat dissipation coefficient of the film, rust scale and surface condition of the metal. Stainless steel keeps its surface tidy and therefore conducts heat better than other metals with higher thermal conductivity.
