1/2H,硬度(HV)250以上
3/4H,310以上
H,370以上.
上面是304的数据,316原始力学性能等同304,冷轧后应该差别不大,——参考. - 1年前

Materials used were F82H and SUS316L plates whose size was100 mm in length,50 mm in width and 4 mm in thickness.Thechemical composition of these materials is shown in Table 1.TheF82H steel was normalized at 1040◦C for 0.5 h and tempered at740◦C for 1.5 h before the welding.
According to our previous study for examining the weldability ofF82H/SUS316L joint welded by the fiber laser,the position of laserbeam was varied from the contact face to SUS316L side,where theshift was set as smaller than 0.2 mm since the diameter of laserbeam was only 0.2 mm [7].Also,the welding speed was varied inorder to examine the effect of heat input on the mechanical prop-erties.Then,the welding conditions were summarized in Table 2.Since,in the practical manufacturing process with fiber laser,a spe-cial jig tool is occasionally employed to control laser beam positionprecisely,an original jig tool was used in this experiment,wherethe laser beam position can be shifted with micrometer order.Therewere various reports about the necessity of post-weld heat treat-ment (PWHT) to the welded F82H joint [2,11] and the EB weldedjoint between F82H and SUS316L for improving their mechanicalproperties [5].So,PWHT was performed at 720◦C for 1 h accordingto the previous studies小猪不平1年前1 -
