introduction
What is electrolytic polishing tube?
Electrolytic polishing (Electro-Polished), referred to as EP. Through electrochemical polishing, the surface morphology and structure can be greatly improved, and the actual area of the surface layer can be reduced to the greatest extent. The surface is a closed, thick chromium oxide film, and the energy is close to the normal level of the alloy.
446 stainless steel pipe is a high-temperature corrosion-resistant steel. Its main components are chromium and molybdenum. It has low carbon content, and its hardness and strength are slightly lower than other stainless steels, but it has high corrosion resistance and high-temperature strength. 446 heat-resistant stainless steel pipe is usually used at high temperatures and can withstand temperatures up to 1093°C. It is suitable for chemical, petroleum, textile, food, paper, electricity and other fields.
Stainless steel 446 pipe is a chromium-molybdenum heat-resistant steel that maintains stable corrosion resistance at high temperatures. It has excellent oxidation resistance and can withstand oxidation, sulfidation and nitridation in the atmosphere. The chromium content in 446 stainless steel is as high as 27%, which can enhance its corrosion resistance. At the same time, the addition of molybdenum can improve its strength and hardness, and can also reduce the cracking tendency of 446 stainless steel thick-walled pipes. Therefore, the control of molybdenum content is very critical. In addition, the carbon content of 446 stainless steel round pipes should be kept below 0.05% to ensure that its corrosion resistance is not affected.
