There are 6 specific reasons why 430 stainless steel pipe is not easy to weld: 1. High thermal conductivity: 430 stainless steel pipes have higher thermal conductivity compared to austenitic stainless steel. This means that they can dissipate heat more effectively, and maintaining the heat required for welding can be challenging. 2. Rapid cooling rate: 430 stainless steel pipes tend to experience rapid cooling rates during welding, especially in thicker sections. This rapid cooling can cause brittle phases such as martensite to form in the heat-affected zone, increasing the risk of cracking. 3. Sensitivity to hydrogen embrittlement: Ferritic stainless steel is more susceptible to hydrogen embrittlement during welding. The welding process introduces hydrogen into the material, which can cause the formation of hydrogen-induced cracks if not managed properly. 4. Sensitivity to hot cracking: 430 ferritic stainless steel is prone to hot cracking, especially in the presence of impurities such as sulfur and phosphorus. The welding process may introduce these impurities, and proper welding techniques (such as preheating and controlling the interlayer temperature) are essential to minimize the risk of hot cracking. 5. Limited ductility at low temperatures: 430 stainless steel exhibits reduced ductility at lower temperatures, and the welding process...
Processing is an important link that affects the quality of color-coated plates. In order to ensure product quality, some precautions during processing are given below for reference. Because color-coated plates have coatings on their surfaces, there are many differences between them and ordinary cold-rolled plates and coated plates during processing. The most important difference is that the forming process must be carried out under the premise of ensuring that the coating is intact. The precautions during processing are as follows: 1. Mechanical properties are an important indicator for measuring formability and an important parameter for determining and adjusting the processing technology. Therefore, they should be considered first during processing. 2. Indicators such as pencil hardness, T-bend, and impact energy are closely related to processing performance, so they should be fully considered. 3. When the shape of the parts is complex and the degree of deformation is large, multi-pass forming should be adopted. If formed in one time, the bonding force between the coating and the substrate may be destroyed due to excessive deformation. 4. During processing, the appropriate gap should be set according to factors such as mold shape, deformation characteristics, and process conditions. The thickness of the coating should...
