Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after crimping unit and mold welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe. Stainless steel welded pipe production enterprises are increasing, but the output of 5000T level of enterprises are very few, especially to produce stainless steel heat exchanger tubes, condensing tubes and other enterprises that need online solution annealing. GB/T12770-2002 (Welded stainless steel tubes for mechanical structures) Mainly used in machinery, automobile, bicycle, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on. GB/T12771-2008 (Welded stainless steel tubes for fluid transport) Mainly used for conveying low pressure corrosive medium. The representative materials are 304, 321, 316, 310S, 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2, etc.
316L stainless steel welded pipe is a kind of basic pipe, so it also has a lot of hard and necessary indicators, including many aspects, the following we want to talk about 316L stainless steel welded pipe hardness indicators. According to the test method and the scope of use is different, the hardness can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro hardness and high temperature hardness. Commonly used to tubing brinell, Rockwell, Vickers hardness 3 kinds. Brinell hardness (HB with a certain diameter of steel ball or hard alloy ball, with the designated test force (F) pressed into the surface of the sample, after the designated hold time to remove the test force, measurement of the sample surface indentation diameter (L) Brinell hardness value is the test force divided by the indentation spherical surface area of the quotient. Expressed in HBS(steel ball), the unit is N/mm2(MPa its calculation formula is: F-- the test force pressed into 316L stainless steel welded tube sample surface, N, D-- the diameter of the test steel ball, MMD -- uniform diameter of indentation, mm. Brinell hardness measurement is more accurate and reliable, but generally HBS only suitable for 450N/mm2(MPa) below the metal materials, for the harder steel or thinner 316L stainless steel welded pipe is not suitable for use. In 316L stainless steel welded tube scale, Brinell hardness is widely used, often to indentation diameter D to express the hardness of the material, both intuitive and convenient.
