904L N08904 stainless steel is a low-carbon, high-alloyed austenitic stainless steel designed for environments with harsh corrosion conditions. It has better corrosion resistance than 316L and 317L, and at the same time, it takes into account both price and performance, and is extremely cost-effective .
Because of the addition of 1.5% copper, it has very good corrosion resistance for reducing acids such as sulfuric acid and phosphoric acid.
904L super austenitic stainless steel also has excellent corrosion resistance to stress corrosion, pitting corrosion and crevice corrosion caused by chloride ions, as well as excellent resistance to intergranular corrosion.
310S stainless steel main components: 25Cr-20Ni-0.08C

310S stainless steel is designed for high-temperature environments, and its oxidation resistance is better than that of 309S stainless steel. It is mostly used as heat-resistant steel and boilers. The maximum service temperature can reach 1300 °C, and the continuous use temperature is 1150 °C.
As a high-performance stainless steel pipe, its tensile strength and high temperature resistance are far beyond other similar varieties.
However, in comparison, 904L stainless steel tubes are not much more resistant to high temperatures than 310S stainless steel tubes. In fact, the two types of tubi in acciaio inox have different uses because of their different composition content. High temperature resistant stainless steel pipe”, 904L stainless steel pipe is usually a stainless steel pipe that can be used in extreme corrosion.
