DIN 1.4571 SS Seamless Pipe, also known as X6CrNiMoTi17-12-2, is a stainless steel under the German DIN standard. Its chemical composition contains 17% to 19% chromium, 12% to 14% nickel, 2.5% to 3% molybdenum, and 0.08% to 0.12% titanium. In addition, it also contains small amounts of carbon, manganese, silicon, phosphorus and sulfur. This stainless steel exhibits good mechanical properties in high-temperature environments and is therefore widely used in high-temperature applications such as petrochemical and chemical processing equipment.
DIN 1.4571 heat-resistant steel pipe has excellent heat treatment properties and can be heat treated at high temperatures to obtain high strength and hardness. In addition, DIN 1.4571 seamless pipe also has good welding and processing properties, and can be processed through various processing methods such as stamping, deep drawing, and bending. It is also ideal for welding methods such as arc, gas and plasma welding.
DIN 1.4571 stainless steel seamless pipe is widely used in various fields including industry, food processing and aerospace due to its high strength, high corrosion resistance and high temperature performance. It is a very excellent steel material that can meet the needs of various complex environments.
