Since its mild steel, it is used directly without heat treatment.See more on theworldmaterialPublished It can be observed that the Q235 steel base metal fractured. Based on the hardness measurement results, the 2205DSS base metal and WS were harder than the of Q235 steel. Therefore, when the stress reached 235 MPa, the Q235 steel plastically deformed. As the plastic deformation processed, the Q235 steel exhibited necking.(plate) Design Guide on Use of Alternative Steel Materials to BS

Q235 steel is the most commonly used metal material, which is widely used in the automobile industry, machinery manufacturing, and chemical industry [13]. However, low hardness and poor wear resistance limit its application in key friction movement parts.
