Description

For the material G12MnMo7-4, which is suitable for great wall thicknesses, the desired properties can be adjusted to a large extent without taking the wall thickness into account because of the materials capability of precipitation hardening. The material possesses an outstandingly low carbon equivalent and, therefore, is still weldable without preheating and subsequent heat treatment with greater wall thicknesses, too. With its mechanical properties and its weldability, G12MnMo7-4 corresponds to the rolled or forged fine-grain structural steels StE 460c and StE 500 and, therefore, presents itself as a good choice for high-strength welded constructions. In addition to high values for the 0.2% proof strength, the material distinguishes itself by relatively high values of the notch impact energy at the same time. Applcation: is chiefly applied in the mechanical engineering and the vehicle manufacturing, furthermore in the plant engineering and crane construction, in the offshore-technology as well as in the underground mining at climatically determined temperatures.
