[美]《Metal Handbook》,vol.4,p.647～649 奥氏体不锈钢具有良好的蠕变抗力,因此必须加热到900℃才能充分消除应力。在某些情况下将钢加热到退火温度比较理想。温度低于870℃时,只能消除部分应力。缓慢冷却也能有效地消除应力。文中介绍了347型不锈钢的应力消除量与除应力温度、保温时间及初始 [United States] “Metal Handbook”, vol.4, p.647 ~ 649 austenitic stainless steel has good creep resistance, it must be heated to 900 ℃ in order to fully eliminate the stress. In some cases it is ideal to heat the steel to the annealing temperature. When the temperature is below 870 ℃, only part of the stress can be eliminated. Slow cooling can also effectively eliminate the stress. In this paper, the stress relief of 347 stainless steel and the stress relief temperature, holding time and initial
