最近,我所接到上海异型铆钉厂委托的一项热处理任务。对不锈钢抽芯铆钉进行热处理。该铆钉材料为1Cr18Ni9,芯子为2Cr13。热处理后技术要求;2Cr13达到HRC42～45,1Cr 18Ni9HV180。热处理后要求变形小,且铆钉表面光亮,不允许有微量氧化色。这种铆钉是新产品,国外市场上很畅销。该厂原来用箱式炉加热水淬,然后酸洗
Recently, I received a heat treatment task entrusted by Shanghai Shaped Rivet Factory. Stainless steel blind rivets heat treatment. The rivet material is 1Cr18Ni9, the core is 2Cr13. Technical requirements after heat treatment; 2Cr13 reaches HRC42 ~ 45, 1Cr18Ni9HV180. Deformation required after heat treatment is small, and rivets bright surface, does not allow traces of oxidation. This rivet is a new product, very popular in foreign markets. The factory originally used a box furnace heated water quenching, and then pickling
