What is the machinability of CR550/980DP dual phase steel?

CR550/980DP dual-phase steel is a high-strength, high-deformation automotive steel with good strength and plasticity, but relatively poor processability, requiring special processing technology.

During cold rolling, the grain size of CR550/980DP dual-phase steel is smaller and the intergranular gaps are smaller, which makes it harder and tougher during forming, but also makes it difficult to process. Due to its high strength and high deformability, higher cutting forces and cutting speeds are required to maintain the life of the cutting edge. At the same time, the strength and plasticity of steel also need to be carefully balanced to ensure that there will be no problems such as breakage or cracks in the processed parts.
