[CN201810623957.X] High creep and corrosion resistant material and method for preparing shell hammerhead by using the material


[CN201810623957.X] A high creep and corrosion resistant material and a method for preparing a shell hammer using the material Title: A high creep and corrosion resistant material and a method for preparing a shell hammer using the material Application No.: CN201810623957.X Applicant: Jiuquan Iron and Steel (Group) Co., Ltd. Application Date: 2018-6-15 Patent Type: Invention Application This invention belongs to the technical field of aluminum smelting, disclosed are a tungsten-containing high creep and corrosion resistance material and a method for preparing a hammer head using the material to solve the problems existing in the shell-beating hammer head material in the prior art. The material includes the following components by weight percentage: C 0.18-0.29%,Cr 23-25%,Ni 9.5-12%,Mn 1-2%,W 1.8-3.4%,Si 0.7-1.2%,B 0.001-0.004%,P <0.05%,S <0.01%, balance Fe. The use of this material smelting, production of steel ingots, forging or hot rolling, segmentation, heat treatment, machine molding and other steps to make a shell hammer. The invention will form a Cr-Ni type austenitic stainless steel matrix with high temperature resistance and electrochemical corrosion resistance under the coordination of the traditional austenitic stainless steel production process. At the same time, due to the existence of tungsten element, the tungsten carbide precipitated phase enters the austenitic stainless steel matrix to form a tungsten carbide precipitated phase skeleton with high creep resistance and high wear resistance and is dispersed and distributed in the shell hammer head material, the hardness, high creep resistance and high wear resistance of the shell hammer head material are significantly improved.
