Product Details

ASTM1045 is a medium carbon steel with good strength. the microstructure is uniform, the wear resistance is good, but the ductility is reduced, the quenching is easy to deformation and cracking, so the heat treatment is very important, Generally used in the normalizing condition, the mechanical properties of higher demand for tempering treatment, annealing and normalizing the machinability is better than tempering. After tempering must be urgently cooled to avoid the occurrence of tempering brittleness. Spheroidization can improve its cutting performance. ASTM1045 is used for manufacturing parts with high strength requirements such as gears, shafts, piston pins, etc., as well as mechanical workpieces, forgings, stamping parts and bolts, nuts, pipe joints, etc.
