一种提高B50A789G类不锈钢材料强度的方法
摘要：
本发明提供了一种提高B50A789G类不锈钢材料强度的方法，其能解决采用常规淬火后空冷的热处理方法后B50A789G类不锈钢材料强度偏低的问题。将B50A789G类不锈钢材料或者B50A789G类不锈钢材料叶片均匀地放入通用的淬火料筐内，然后再将淬火料筐放入淬火加热炉内加热后保温，再对B50A789G类不锈钢材料或者B50A789G类不锈钢材料叶片进行冷却处理，其特征在于：冷却处理为水冷处理，将B50A789G类不锈钢材料或者B50A789G类不锈钢材料叶片放入水槽内并保持2小时～6小时，水槽内冷却水温度为0℃～26℃。
摘要（英）：

The invention provides a method for improving strength of B50A789G stainless steel materials. The method can solve the problem of low strength of the B50A789G stainless steel materials after the conventional air-cooling thermal treatment method after quenching is adopted. The B50A789G stainless steel materials or the B50A789G stainless steel material blades are evenly put into a universal quenching material basket, and then the quenching material basket is put into a quenching heating furnace to keep warm after being heated; the B50A789G stainless steel materials or the B50A789G stainless steel material blades are cooled. The method is characterized in that cooling treatment is water-cooling treatment; the B50A789G stainless steel materials or the B50A789G stainless steel material blades are put into a water tank and kept for 2-6 hours; the temperature of cooling water inside the water tank is 0-26 DEG C.
