1, Material composition
444 stainless steel pipe is composed of low-carbon chromium molybdenum steel and elements such as copper, molybdenum, iron, and manganese. Compared to 316L stainless steel pipes, it has a higher copper content and a more pronounced silver white color, but it does not affect its corrosion resistance. The addition of copper can improve the chloride resistance of stainless steel, reduce dielectric loss and dielectric constant, and make it more stable under high temperature and high humidity conditions.
2, Strength and toughness
444 stainless steel pipe has excellent strength and toughness, suitable for working environments with high strength and high temperature. This type of steel is well matched with the technology, which can break through the level of friction line, improve durability and anti-corrosion performance. This type of steel has better performance in situations that require high temperature, strength, and corrosion resistance.
3, Cost performance ratio
444 stainless steel pipe is more cost-effective than 316L stainless steel pipe in terms of price, and its manufacturing cost is relatively low, providing a higher cost-effectiveness. Meanwhile, compared to traditional 304 and 316L stainless steel pipes, this type of stainless steel pipe can achieve better use and service life under low temperature and strong vortex conditions.
4, Application field
444 stainless steel pipes have important applications in fields such as construction, chemical engineering, machinery, and shipbuilding. This type of steel is suitable for various purposes such as water pipes, chemical pipelines, petroleum, agricultural irrigation, compressed air pipelines, as well as engineering materials, pressure vessels, water pump valves, etc. It is used in the shipbuilding industry as a ballast tank, oil storage tank, fire equipment, etc. In the automotive and home appliance industries, 444 stainless steel pipes also have unique applications.
