There are significant differences between stainless steel pipes and galvanized pipes in many aspects: First of all, from a material perspective, stainless steel pipes are made of high-quality stainless steel and have excellent corrosion resistance, high temperature resistance and high strength properties. In contrast, galvanized pipe is coated with a layer of zinc on the surface of the steel pipe through electroplating or hot-dipping, aiming to enhance its corrosion resistance. However, the material properties of stainless steel pipes are significantly better than galvanized pipes. Secondly, from the perspective of appearance and service life, the surface of stainless steel pipes is smooth, beautiful and not easy to rust, thus ensuring long-term use. In contrast, galvanized pipes are prone to rust on their surfaces, affecting their appearance and service life. In addition, the relatively light weight of stainless steel pipes makes them easier to handle and install, while galvanized pipes are relatively heavier. In terms of application scope, due to its excellent performance and wide range of application fields, stainless steel pipes are widely used in various industries. For example, it is used in the petrochemical industry to transport corrosive media; in the food industry, it is used in pipelines to transport...
In today’s industrial and construction fields, stainless steel pipes have become an indispensable and important material with their excellent performance and diverse uses. Among them, 201 stainless steel pipes stand out among many stainless steel pipe products with their unique advantages. 1. Performance characteristics of 201 stainless steel pipes Good corrosion resistance 201 stainless steel pipes contain a certain amount of chromium and nickel elements, which make them have good corrosion resistance in general environments and can resist the erosion of atmosphere, water and some weakly corrosive media, thereby extending the service life of the pipes. High strength and toughness After special processing technology, 201 stainless steel pipes have high strength and toughness, can withstand greater pressure and impact, and still maintain stable performance under complex working conditions.

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...
