310S stainless steel
seamless tube
310S ( 0Cr25Ni20 ) stainless steel seamless tube.310S austenitic stainless steel for high temperature environment. The higher content of chromium and nickel content to ensure good corrosion resistance and antioxidation. And Austenitic Alloy 304 is compared, at room temperature strength should be higher.Product introduction[ a ] the production specifications ( mm ): White 6 x 1 to 830 x 20 ( can be customized according to customer requirements )[ two ] finished length (m ): 5 - 7 ( can be customized according to customer requirements ), part of the long and up to 28m[ three ] product material: 310S ( 0Cr25Ni20 )[ four ] theoretical weight ( kg / M ): you you you you you Cr-Ni austenitic stainless steel you you you W = 0.02491S ( D-S )[ five ] Executive standard:GB: GB / T14975-2002 GB / T14976-2002 GB / T13296-2007 ASTM A312 / A312M ASTM American Standard: A269 / 269M ASTM A213 / 213AProduct characteristicsChemical analysis:Grade chemical composition ( mass fraction), %C ( carbon ) Si ( silicon ) Mn (MN ) P ( P ) S ( sulfur ) Ni ( nickel ) Cr ( CR ) Mo ( MO) other0Cr25Ni20 = 0.08 = 1 = 2 = 0.035 = 0.030 19 - 22 24 - 26 -In 2, the hydraulic test:On the seamless tube of stainless steel by root hydraulic pressure test, the set pressure value, maintain not less than 5 seconds. Steel pipe or water leakage or seepage, regular supply hydraulic pressure test for P = 2SR / D ( maximum 20MPa ). 3, corrosion resistance:The intergranular corrosion resistance and excellent corrosion resistance to alkali solution, and most organic and inorganic acid also has a certain ability to resist corrosion for stainless steel seamless pipe, according to the standard or agreement corrosion method for corrosion inspection, there shall be no intergranular corrosion tendency. 4, process performance test:Flattening test, tensile test, the flaring test, hardness test, metallographic examination, nondestructive testing ( including eddy current inspection and ultrasonic inspection ).In 5, high temperature oxidation resistance of:High temperature oxidation leads to a passivation layer. The heat-resistant stainless steel surface formation of chromium oxide, starting with Cr2O3, when the temperature rises further, will be further oxidized to having a high vapor pressure CrO3. Oxide at this time is divided into two parts : through the formation of Cr2O3 make rust skin thickening, through the CrO3 evaporation so that the passivation layer thinning. The final trend in thickening and thinning between ultimate balance, so that the scale is in a constant thickness. Rust peel volatile at temperatures up to 1093 degrees above C, became a prominent problem, in the flow of gases, will further worsen.
