It is widely used in buildings and engineering structures. It is used to make steel bars or to build workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, vessels, ships, etc., and is also widely used as mechanical parts with low performance requirements. Grade C and D steel can also be used as some professional steel.2. It can be used for various mold handles and other unimportant mold parts.3. Q235 steel is used as the punch material, which is directly used without tempering after quenching, and the hardness is 36~40HRC, which solves the problem of the punch breaking in use.Q235 ordinary carbon structural steel is also called A3 steel.Q represents the yield limit of this material, and the following 235 refers to the yield value of this material is about 235MPa. The yield value of the material will decrease with the increase of its thickness. Due to the moderate carbon content, good comprehensive performance, and good coordination of strength, plasticity, welding and other properties, it is the most widely used.
