What is the use of graded quenching of stainless steel seamless elbows?
Wenzhou Licheng Steel Industry Co., Ltd. is a modern enterprise specializing in the production of stainless steel pipes, pipe fittings and flanges. We have professional technical strength and advanced team management capabilities. Brands include: 304.304L.304H.321.321H.316.316L.317L.310S.347H, etc. Pipe size range (6mm-580mm)*OD(2mm-40mm)WT*4000-15000mm)Length. With good reputation, positive service and other favorable conditions, we provide you with high-tech and competitive products.
The graded quenching of stainless steel seamless elbow is to immerse it in a liquid medium with a relatively high temperature or slightly lower than the martensitic point of stainless steel, such as a salt bath or an alkali bath, and keep it for a certain period of time until the inner and outer layers of the steel part reach the medium Take out the air cooling after the temperature to obtain the quenching process of the martensitic structure.
So as the title, what is the use of graded quenching?
Because the graded quenching is air-cooled after the graded temperature stays at the same temperature inside and outside the workpiece, it can effectively reduce the phase transition stress and thermal stress, and reduce the deformation and cracking tendency of quenching.
Staged quenching is suitable for alloy steel and high alloy steel workpieces that require high deformation, and can also be used for carbon steel workpieces with small cross-sectional dimensions and complex shapes.
