Forging is a process of using forging machines to pressure the steel billet and produce the plastic deformation to get the certain mechanical properties, shape and size. Forging and pressing are two main parts. This process can eliminate the weakness of loose cast condition in smelting process and optimize the microstructure. Due to the process of forging saving the whole flow line, the properties of forgings are better than other products in same material.Most of the parts in high load and serious work condition are forgings. In general, the forgings are for transmission shaft or shaft under high torque and load, like marine shafting(providing the certificate of classification societies). Currently, the available size: 80mm-800mm. Main material:20Cr、40Cr、15CrMo、20CrMo、35CrMo、40CrMo、42CrMo、40CrNiMo、28SiMnVB、30SiMnVB、30MnCrB5、SCM415、SCM420、SCM420、SCM440、20CrNiMo、40CrNiMo、SNCM220、SNCM439、SCr420、SCr440、20X、40X、45X、SAE5120、SAE5140、SAE5145、SCr445、12XM、15XM、20XM、30XM、35XM、38XM、SCM430、SCM435、SAE4118、SAE4130、SAE4135、SAE4140、38CrMoAl、SACM645、E7140、Y12Pb、AC14、SUM22L、SUM24L、12L14、20Cr4、17Cr13-1.7016、41Cr4、15XM、13CrMo44、18CrMo4、25CrMo4、34CrMo4、34CrMo4、41CrAlMo74、20CrMnTi
