Performance requirements of stainless steel flange materials
Elastic limit and high fatigue strength of stainless steel flange material. In the process of stainless steel flange material, 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 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, and their carbon content is slightly lower, which mainly depends on increasing the silicon content WSI to improve the performance; 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, which has extended the service life of springs made of stainless steel flanges and improved the quality of springs.
Die steel made of stainless steel flange can be roughly divided into cold-rolled die steel, hot-rolled die steel and plastic die steel, which are used for forging, stamping, cutting, die casting, etc. Due to the different uses and complex working conditions of various moulds made of stainless steel flange, the steel for moulds made of stainless steel flange should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardenability and other process properties according to the working conditions of the moulds manufactured. Due to the different uses of this kind of stainless steel flange materials and complex working conditions, the performance requirements of die steel are also different.
