After high temperature forging and compression deformation, the metal material of the forged shaft has a denser grain structure, thus achieving higher strength and toughness than other processing methods. After quenching and tempering, the tensile strength of 4140 steel can reach more than 1080MPa and the yield strength can reach more than 930MPa.
After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
4140 steel forgings have good strength and endurance performance at high temperatures.
Our steel forgings are widely used in wind power industry, chemical industry, machinery industry, automotive industry, marine industry, power plant industry, metallurgy industry, mining industry, petrochemical industry and other industries.
