Austenitic stainless steel pipe welding process: Shandong Jinding Stainless Steel Pipe Co., Ltd. is a professional manufacturer of stainless steel pipe enterprises, the main processing boiler and heat exchanger with stainless steel pipe, a perfect process equipment and testing equipment. Included within the weld leveling process line bright solution heat treatment. And with a line eddy current testing, hydrostatic testing, mechanical and process performance testing, intergranular corrosion and metallographic inspection equipment. Products can be Chinese GB / T-2008, GB / T24593-2009, the United States ASTM, A249, A312, Japanese JIS, German DIN and other standards of production. The main production 304,304L, 316,316L, 321,409, food grade stainless steel pipe, thin-walled stainless steel pipe, industrial piping, heat exchangers, stainless steel pipe, low pressure (12 class) tube. Quality assurance and affordable. Austenitic stainless steel magnetic control: by using Ar + N2 mixed gas instead of 100% pure argon gas tungsten arc welding, 304 stainless steel pipe [factory], and the use of domestic H00Cr21Nilo wire 304L material for welding procedure tests, test results show : 1, using 100% pure welding, weld permeability of about 1.1, can not meet the design requirements; 2, when the argon adding a certain percentage of nitrogen, after welding seam permeability of less than 1.1, meet the design requirements , [precision] 304 stainless steel, further analysis of the weld microstructure of austenite and ferrite very small; 3, when more than a certain amount of nitrogen, the weld permeability of less than 1.1, the pressure vessel [304] pipe, to meet requirements of the drawings, but instability in the welding process, the welding process a large number of spatter, easy to produce weld porosity; 4, as long as the control volume ratio of nitrogen and argon, can ensure that the weld permeability of less than 1.1, and can good mechanical properties; 5, using tungsten Ar + N2 mixed gas shielded arc welding instead of welding practicable, the indicators can meet the design requirements, greatly reducing the cost of consumables developed and good process performance. 316L stainless steel welded pipe is the most basic, so it also has a lot of hard and fast but also necessary indicators, Shandong Jinding Stainless Steel Pipe Co., Ltd. Online Service Description: hardness index on 316L stainless steel welded pipe Hop application according to the test methods differ, can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro hardness and high temperature hardness, etc. For pipe commonly used are Brinell, Rockwell, Vickers hardness of three. For hard or thin steel 316L stainless steel pipe used substandard in 316L stainless steel pipe scale, the most widely used Brinell hardness, 304 stainless steel, often indentation diameter d to represent the hardness of the material, both intuitive and convenient. as World Business provide the best quality of industrial metal pipe Shandong Jinding Stainless Steel Pipe Co., Ltd.'s mission. The company mainly produces stainless steel pipe boilers and heat exchangers, condensers with stainless steel pipe, automobile exhaust system with a stainless steel pipe and process piping. 304 stainless steel pipe, King tube industry, [] 304 stainless steel pressure vessel provided by the Shandong Jinding Stainless Steel Pipe Co., Ltd .. 304 stainless steel pipe, King tube industry, [] 304 stainless steel pressure vessel Shandong Jinding Stainless Steel Pipe Co., Ltd.
