1030 steel round bar is a kind of high-quality carbon structural steel. 1030 has a certain strength and hardness. 1030 steel round bar plasticity and weldability are better. 1030 steel round bar is usually used under the condition of normalizing, also can be hardening and tempering. After hardening and tempering. 1030 has better comprehensive mechanics properties and better machinability.
