904L Seamless steel pipe Features
904L stainless steel pipe (00Cr20Ni25Mo4.5Cu) is austenitic stainless steel with better corrosion resistance. Because 1.5% copper is added, it also has excellent corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid. In addition, It has low carbon characteristics for welding applications.
The product has high strength, is not easy to rust, and has good heat insulation effect. It is suitable for new construction, reconstruction, and expansion projects that require waterproofing, heat insulation, heat preservation, leakage prevention, and water cooling. It has a wide range of application prospects. The easy-cut seamless pipe adopts a unique micro-hole design, which makes full use of the micro-hole space and flange, and at the same time, it is fastened by aluminum row bolts, which can obtain a close-fitting welding connection. It makes full use of the advantages of welding materials and is not compatible with vacuum cutting. Compared with the seam pipe, the cost is low, the economy is good, and the pressure resistance is strong
904L (N08904, 14539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel, and 4.5% molybdenum. 904L super austenitic stainless steel is a low-carbon, high-nickel, molybdenum austenitic stainless and acid-resistant steel. It is a proprietary material imported from France H·S. It has good activation-passivation conversion ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and good corrosion resistance in neutral chloride-containing media It has good pitting resistance and good resistance to crevice corrosion and stress corrosion. It is suitable for sulfuric acid of various concentrations below 70°C, and it is resistant to acetic acid of any concentration and temperature under normal pressure, and the corrosion resistance in the mixed acid of formic acid and acetic acid is also very good.
