Analysis of the Fracture Failure of 201 Stainless Steel Strip

Energy storage battery module fixed with 201 stainless steel belt in the process of ultimate failure vibration test fracture risk, for further study of 201 stainless steel belt in the process of the ultimate failure vibration test stainless steel belt fracture related data, through the macro and micro fracture morphology observation, metallographic detection, hardness test and chemical cost analysis method for failure analysis. The results show that the fracture mode of steel belt is brittle overload fracture. The strength factor of raw materials has a certain influence on the plastic toughness, thus affecting the ability to resist deformation and fracture. At the same time, the surface quality of the steel belt is also an important factor. If there are cutting scratches and wrinkles on the crack side, it will cause stress concentration and become a relatively weak part when the steel belt is stressed.
