3Cr13不锈钢管钢标准:GB/T1220-1992,属马氏体类型不锈钢,该钢机械加工性能好,经热处理(淬火回火)后,具有优良的耐腐蚀性能抛光性能较高的强度和耐磨性,适宜制造承受高负荷,高耐磨及在腐蚀介质作用下的塑料模具。调质处理后硬度在HRC30以下的3Cr13材料加工性较好,易达到较好的表面质量。而硬度大于HRC30时加工出的零件,表面质量虽然较好,但刀具易磨损。所以,在材料进厂后,先进行调质处理硬度达到HRC25~30,然后再进行切削加工。
3Cr13 stainless steel pipe steel standard: GB/T1220-1992, it is a martensitic stainless steel, this steel has good machining performance, after heat treatment (quenching and tempering), it has excellent corrosion resistance, polishing performance, high strength and wear resistance It is suitable for manufacturing plastic molds that bear high load, high wear resistance and corrosive media. After quenching and tempering, the 3Cr13 material with a hardness below HRC30 has better workability and is easy to achieve better surface quality. The surface quality of the parts processed when the hardness is greater than HRC30 is good, but the tool is easy to wear. Therefore, after the material enters the factory, the quenching and tempering treatment is carried out to reach the hardness of HRC25-30, and then the cutting is carried out.
