摘要
采用不同的始锻温度和终锻温度进行了F40-0.2Cr新型不锈钢的锻压试验,并进行了不锈钢法兰试样磨损性能和腐蚀性能的测试与分析。结果表明:在试验条件下,随始锻温度从975℃增大到1075℃或随终锻温度从800℃增大到900℃时,不锈钢试样的磨损性能和腐蚀性能均先升高后下降。不锈钢的始锻温度和终锻温度分别优选为1050、850℃。在其他条件相同的情况下,与975℃始锻相比,1050℃始锻时不锈钢试样的磨损体积减小45%,腐蚀电位正移151 m V;与800℃终锻试样相比,850℃终锻时不锈钢的磨损体积减小42%,腐蚀电位正移134 m V。
The forging test of F40-0.2Cr new type stainless steel was carried out by using different initial forging temperature and final forging temperature. And the wear resistance and corrosion resistance of the stainless steel flange were tested and analyzed. The results show that under test conditions, with the initial forging temperature increasing from 975℃ to 1075℃ or the final forging temperature increasing from 800℃ to 900℃, the wear resistance and corrosion resistance of the stainless steel samples improve firstly and then decrease. The optimized initial forging temperature and final forging temperature are 1050℃ and 850℃, respectively. In the same conditions as others, compared with the sample of the initial forging at 975 ℃, the wear volume of the stainless steel sample forged by the initial forging at 10750C decreases by 45%, while the corrosion potential shifts positively by 151 mV. Compared with sample of final forging at 800℃ ,the wear volume of the stainless steel sample forged by the finial forging at 850~C decreases by 42% and the corrosion potential shifts positively by 134 mV.
