Why is Q420C steel plate not suitable for gears making Q420C steel plate is a low-alloy high-strength structural steel. The yield strength of Q235 is 235MPa, while the yield strength of Q420 is 420MPa. Because of its low carbon content, it cannot be processed by quenching and tempering, and it is still unable to process shafts and gears. Q420C Welding properties of Q420C steel plate steel plate In the Q420C steel plate welding process, the metal in the welding cone and heat-affected zone undergoes a series of complex processes such as heating, melting, crystallization, cooling, state phase change, stress and strain.
