Chemical composition:
It belongs to low-carbon steel, with a carbon content of about 0.15% -0.2%, manganese content of 0.6% -0.9%, phosphorus content not exceeding 0.03%, and sulfur content not exceeding 0.035%.
Production process:
High quality hot-rolled bars are usually used as raw materials, and are made through processes such as cold drawing, turning, grinding, polishing, or a combination of multiple processes. Cold processing can improve its yield strength and tensile strength, making dimensional accuracy more precise and surface smoother.
Performance characteristics:
It has good machinability and cutting performance up to 62% of 1112 carbon steel. Excellent welding performance, can use various welding methods such as gas welding, resistance welding, etc. At the same time, it has good formability and is easy to process and shape in the annealed state.
Mechanical properties:
The tensile strength is about 70ksi (about 483MPa), the yield strength is about 58ksi (about 400MPa), the elongation is 15%, the Brinell hardness is 126, and the Rockwell hardness is 71.
