摘要 通过调整合金元素含量、生产工艺流程和研磨工艺,并对制备的产品试样进行了表面形态评定和耐腐蚀性试验,研究了影响电梯用439不锈钢耐腐蚀性的因素。结果表明:适当提高铬元素含量,采用先研磨后退火酸洗的工艺以及控制研磨过程中研磨砂带粒度和研磨介质中硫元素的含量,可提高439不锈钢的耐腐蚀性。 The influencing factors were studied that relate to the corrosion resistance of 439 stainless steel used in elevators,through surface morphology evaluation and corrosion resistance test for the samples whose alloy element contents,production process and grinding technology were adjusted.The results showed that the corrosion resistance of 439 stainless steel can be improved by improving Cr content,adopting the technology of first grinding and then annealing and pickling,controlling the particle size of abrasive belt and S content of abrasive materials.
