High temperature resistant seamless custom steel pipeline

　　High temperature seamless custom steel pipeline resistance is excellent. It has high temperature strength, oxidation resistance, carburization resistance, acid resistance, alkali resistance, tensile strength and wear resistance, and the continuous use temperature is 1150 ℃. The common working temperature should not exceed 1050 ℃, and the maximum temperature should not exceed 1200 ℃. The higher the carbon content, the higher the hardness, but the worse the plasticity and toughness.

　　Sulfur is a harmful impurity in steel. When the steel with high sulfur content is processed under high temperature and pressure, API 5L ASTM A106 Grade B Seamless Custom Steel Pipeline is easy to be brittle, which is usually called hot brittleness. Phosphorus can obviously reduce the plasticity and toughness of steel, especially at low temperature. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. On the other hand, high sulfur and phosphorus in low-carbon steel can make it cut easily, which is beneficial to improve the machinability of steel. Manganese can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties.

　　In recent years, antibacterial and high temperature resistant seamless custom steel pipeline are the new favorite of stainless steel family. It is made by adding some antibacterial elements such as copper and silver to seamless custom steel pipeline through special treatment. This excellent antibacterial and self-cleaning property indicates that it has a very broad application prospect. The high temperature resistant seamless custom steel pipeline has good oxidation resistance in the discontinuous use below 1600 ℃ and continuous use below 1700 ℃. In the range of 800-1575 ℃, it is better not to continuously act on the high temperature resistant seamless custom steel pipeline, but when the high temperature resistant seamless custom steel pipeline is continuously used outside the temperature range, the seamless custom steel pipeline has good heat resistance. The carbide precipitation resistance of high temperature seamless custom steel pipeline is better than that of 316 stainless steel, and the above temperature range can be used.
