In practical application, the corrosion resistant steel is often called stainless steel, and the corrosion resistant steel is called acid resistant steel.The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.Because of their differences in chemical composition, the former is not necessarily resistant to chemical medium erosion, while the latter is generally rustproof.Difference between precision steel tube and seamless steel tubeThe product can be very rough cast
The heat resisting seamless steel tube for boiler is under the condition of high pressure and high temperature, the material will be creep, plastic and toughness decline, the original structure change, corrosion and so on.Therefore, heat-resistant steel for boilers should have :1) high temperature strength, 2) high plastic deformation capability, 3) minimum aging tendency and hot brittleness, 4) adequate corrosion resistance and coordination, and 5) good process performance.
