Product Description

Based on the good relationship with steel mill, EB can always meet with the special demands from our customers. The
special 42CrMo4 raw materials for ring gear forgings is the good reference. This kind of raw material 42CrMo4 with higher
S comtent than the standard, the standard 42CrMo4 only with around 0.005% S content, but our customer made 42CrMo4
materail with the higher S contents 0.02% than the standard, the higher S content can improve the machinability, it is the
benifits for tools when broaching the gear rings.

In additionally, according to our customer's demands, every raw material bars in 42CrMo4 must be tested by magnetic
particle, chemical analysis ,grain sizes , cleanliness and hardenability.

Thanks for our advanced forging equipments and excellent forging techanicals, our company had the most advantages
in the field of ring forging, heavy die forging, stainless steel forging, aluminium forging, difficult forging parts. We also
had kinds of machining equipments in our own workshop, such as lathes, CNC lathes, milling machines, drilling machines,
CNC machining centres,etc.

Try from us, just give your demands and drawings, we will be your right partner.
