Product Show
In the process of polishing, it is found that the welding seam and heat treatment site are corroded, especially the plasma cutting surface. When heating the elbow, serious corrosion occurs in the heated part.
Stainless steel for alloy material, there are different crystal phase, temperature changes when the crystal phase changes accordingly. Therefore in the stainless steel processing process (such as machining, casting, welding and cutting, etc.), one is affected by the temperature local easily precipitated new phase (local phase change), the physical and chemical state of the material between grain boundaries and the grain itself is different, resulting in the grain boundary at the corrosion speed is significantly greater than the grain itself (intergranular corrosion). The precipitation of these new phases will inevitably lead to the formation of some elements in the poor area, whether the precipitation of the new phase corrosion resistance, or corrosion resistance will lead to the uneven corrosion velocity, pitting or pitting. Second, it is easy to produce internal stress under the influence of processing temperature, and a large number of chloride ions aggravate stress corrosion. In the plasma cutting process, high local temperature causes coarse austenitic stainless steel grains, even local melting, excessive internal stress, stress corrosion is particularly obvious.
