310S Stainless steel seamless pipe is a kind of long steel with hollow section and no joint around it.The process of this product determines its limited performance. Generally, the precision of seamless steel tube is low: uneven wall thickness, low brightness inside and outside the tube, high cost of length fixing, and there are pits and black spots on the inside and outside surface which are not easy to remove; its detection and shaping must be off-line processed. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials.

Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials.
Widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transport pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also often used in the production of conventional weapons, barrels, shells and so on
Details for 310S seamless,applications
310S stainless steel (2520) high temperature resistant steel pipe; 310S stainless steel (2520) has good oxidation resistance, corrosion resistance, acid-salt resistance and high temperature resistance due to the high content of nickel (Ni) and chromium (Cr). The high temperature resistant steel pipe is specially used in the manufacture of electric heating furnace tubes and other occasions. Nickel has high strength and creep strength at high temperature because of its face-centered cubic structure, which is based on the addition of molybdenum, tungsten, niobium and titanium.
