Other classification methods of stainless steel flange materials
In addition to the above, there are other classification methods of stainless steel flange materials, such as:
According to different delivery conditions of stainless steel flanges, they can be divided into stainless steel flanges delivered according to chemical composition (mechanical properties) and hardenability. According to the working conditions of the spring made of stainless steel flange, it can be divided into spring steel bearing static load, spring steel bearing impact load, high (low) temperature resistant spring and corrosion-resistant spring steel.
Process performance of stainless steel flange material
The spring made of stainless steel flange is used under impact, vibration or long-term cross stress, so the spring steel is required to have high tensile strength, elastic limit and fatigue strength. In terms of technology, spring steel is required to have certain hardenability, not easy to decarburize, good surface quality and other carbon spring steel, that is, high-quality carbon structural steel made of stainless steel flange with carbon content WC in the range of 0.6% - 0.9%. The alloy spring steel made of stainless steel flange is mainly silicon manganese steel. The carbon content of stainless steel flange is slightly lower, and the performance is mainly improved by increasing the silicon content WSI; In addition, there are chrome, tungsten and vanadium alloy spring steels. In recent years, combined with Chinese resources and according to the requirements of new technologies for automobile and tractor design, a new steel type with boron, niobium, molybdenum and other elements added to silicon manganese steel has been developed as a stainless steel flange material, which extends the service life of the spring and improves the quality of the spring.
