Characteristics of G18NiMoCr36

G18NiMoCr36 is hugely strong and resistant to fracture and cracking. The material can be used at temperatures from -40 °C up to +40 °C. It is used to make highly stressed components in gearboxes and transmission systems in vehicles such as trucks, buses and construction site vehicles. It is also a suitable material for manufacturers of systems and equipment which require weldability and good mechanical properties.

This material is categorised as a high-strength steel. It is delivered with a certificate. The special heat treatment process makes this material suitable for parts used in cranes, heavy military vehicles and shipping.
