310 stainless steel is austenitic chrome-nickel stainless steel with good oxidation resistance and corrosion resistance because of the higher percentage of chromium and nickel.
310S stainless steel is austenitic chrome-nickel stainless steel with good oxidation resistance and resistance corrosive, high temperature resistance, because of a higher percentage of chromium and nickel, so that it has much better creep strength, can continue to work at high temperatures, and has good high temperature resistance. Due to high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance and high temperature resistance. High temperature resistant steel tubes are specially used for the manufacture of electric heating tubes, etc., and carbon is added to austenitic stainless steel. After the content, the strength is improved by the solid solution strengthening effect. The chemical composition of the austenitic stainless steel is based on chromium, nickel and other elements such as molybdenum, tungsten, niobium and titanium. Since the structure is a face-centered cubic structure, Thus there is high strength and creep strength at high temperatures. The melting point of 1470 ° C, 800 ° C began to soften, the allowable stress continued to decrease.
The carbon content of 310H (UNS S31009) is limited to the lower limit of the range of 310. This makes the 310H the preferred grade for high temperature applications. This steel has a good oxidation resistance at intermittent use temperatures up to 1040 ° C (1904 ° F) and continuous use at 1150 ° C (2102 ° F). It is widely used in environments where sulfur dioxide gas is present at high temperatures;
Manufacturing process for 310S/310H stainlesss steel seamless pipe：
Round tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (inspection) → mark → in Library.
