The production of cold rolled 5Cr15MoV martensite stainless steel wide strip(1 200 mm) in China is still in the blank at present

therefore

studying on the process of cold rolling and hot treatment after rolling is of great importance to the product structure optimization and market broadening.The edge carbide precipitation of this steel grade is uneven due to its martensite organization at hot rolled state

with high hardness and low plasticity

its edge crack could be effectively prevented by equalization heat treatment before cold rolling and improving organization form;through trail

cold rolling can be smoothly completed by 20 high Sandzimer Mill with less tension

less screwdown and rolling speed below 100 m/min;after rolled

temperature of cold continuous annealing plate should be controlled between 700～750 ℃ with small coiling tension in order to avoid bending above 180° and the risk of strip breakage.
