Typical ferritic stainless steels are Crl, Cr and Cr.China's numbering rules adopt the use of element symbols and Chinese pinyin. Open hearth steel: P, boiling steel: killed steel: class a steel: T: Special: ball bonded steel and spring steel, such as CrMnTi simn, (C content is expressed in tens of thousands)Since the beginning of last year, foreign countries have frequently carried out & ldquo; Double inverse & rdquo; This has a great impact on China's stainless steel casting industry. Export is a large part of the development of China's stainless steel industry and occupies a huge market share in its industrial development. In the face of economic downturn and slow development, the development of China's stainless steel industry should constantly improve product quality, combine products with environmental protection, energy resources and cultural environment, and improve the competitiveness of stainless steel products. Only in this way can we achieve an invincible position in foreign trade.offer,As long as the steel type is selected correctly and maintained properly,EcatepecStainless steel mop tube, stainless steel will not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the high-strength materials in metal materials for construction. Because stainless steel has good corrosion resistance, it can ensure that the structural components can maintain the integrity of engineering design. Chromium containing stainless steel also integrates mechanical strength and high extensibility and is easy to wear The processing and manufacturing of parts can be fullMeet the needs of architects and structural designers.Human factors are also one of the causes of product oxidation that some consumers often encounter when using stainless steel products. Some consumers operate improperly in product use and maintenance, especially some stainless steel pipe products used in food and chemical equipment industry. For the artificially generated oxidation of steel products, they should have correct product use knowledge and Reasonable and effective maintenance shall be carried out regularly to reduce oxidation caused by improper use.
Restate the quality of stainless steel pipe, we promise & ldquo; chromium and nickel & rdquo; Penalty for false and provide quality inspection report and certificate of conformity.Industry management,Inspection: after crimping, check the crimping size with a special gauge.The effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions, both complex stabilizer HF and adsorption complex stabilizer -sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer -sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling.
