High temperature resistant seamless pipe

High temperature resistant seamless pipe

Excellent high temperature oxidation resistance. It has high high temperature strength, oxidation resistance, carburization resistance, strong acid resistance, alkali resistance, tensile strength and wear resistance. The higher the carbon content of elemental carbon, which has an effect on the performance of high temperature resistant stainless steel pipes, the higher the rigidity, but the worse its plasticity and toughness. Sulfur is a harmful impurity in steel. Steels with high sulfur content are prone to brittleness during pressure processing at high temperatures, which is often called hot brittleness. Phosphorus can significantly reduce the plasticity and toughness of steel, especially at low temperatures. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus must be strictly controlled. However, from another aspect, the low carbon steel contains high sulfur and phosphorus, which can make it easy to cut, 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. performance. The antibacterial and high temperature resistant stainless steel pipe products that have appeared in recent years are the new darlings of the stainless steel family. It is made by adding some antibacterial elements such as copper and silver to stainless steel after special treatment. This excellent antibacterial self-cleaning property indicates that its application prospect is very broad.
