In recent years, an increasing number of stainless steel welded pipe producers, but the level of production reached 5000t very few companies, especially the need to produce online solution annealed stainless steel heat exchanger tubes, condenser and other enterprises is scarce. Only in southern China, Jiangsu, Zhejiang, Jiangsu, Taiwan and other area businesses; only in northern Shandong Jinding Stainless Steel Pipe Industry Co., Ltd., a company is to produce 2000t below most other small plants, and only the production of several common specifications ordinary pipe. Our Stainless Steel Pipe Co., Ltd. Shandong passed ISO / TS16949 quality management system certification, ISO9001-2008 international quality system certification. And a number of European, American, GB certification. Shandong Jinding Stainless Steel Pipe Co., Ltd. is a professional production of stainless steel pipe manufacturers, has focused on the production of stainless steel welded pipe, stainless Why use it as a production material, here we analyze the material in terms of their differences? Applications austenitic and ferritic stainless steel is relatively wide, they have their own distinct characteristics, application there are essentially different, they want to know their purpose, it should know their characteristics and differences. First of all we are saying is austenitic stainless steel under Let us understand the characteristics of austenitic stainless steel welded pipe, stainless austenitic stainless steel is the most important type of stainless steel pipe 316l, which accounts for the total production of stainless steel 70%. According to alloying methods, austenitic stainless steel can be divided into chrome-nickel steel and iron-chromium-manganese steel two categories. The former nickel austenitic elements, is the subject of austenitic steels; the latter is based on manganese, nitrogen instead of expensive nickel-nickel steel. Generally speaking, good corrosion resistance of austenitic 409 stainless steel welded pipe, with good mechanical properties and process performance, but the strength, low hardness. Besides ferritic stainless steels, ferritic stainless steel containing chromium 11% -30%, substantially free of nickel, nickel steel is a section in the organizational structure of the use of state-based ferrite. High strength ferritic stainless steel body and lower work hardening tendency, resistance to chloride stress corrosion, pitting, crevice corrosion, localized corrosion fine, but sensitive to intergranular corrosion, poor low-temperature toughness. 304l stainless steel pipe, Jinding Industry (certified), stainless steel pipe provided by Shandong Jinding Stainless Steel Pipe Co., Ltd. Shandong Jinding Stainless Steel Pipe Co., Ltd. (www.jdbxg.cn) is Dezhou, steel leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
