With the development of industry and the emergence of new technologies, there is a need for new structural materials capable of efficiently and reliably operating under the influence of high loads, the influence of an aggressive environment and significant temperature indices. Today, a lot of materials are known that meet the above requirements, but, despite some similarity, each alloy differs from the others in its individual features that determine the parameters of operation. Alloy cobalt 6b is a continuation of the stellar galaxy of heat-resistant construction materials of a new generation.


Advantages of the alloy are predetermined by its chemical composition. The basis of the unique alloy of cobalt 6b is cobalt and chromium. They give the material not only resistance to high-temperature modes of the working area, but also to the harmful effects of most aggressive industrial environments. Even in the harshest conditions, equipment made from cobalt 6b is characterized by high performance for a long time.

Percent composition
C Mn Si Cr Ni Mo Co Fe W
0.9−1.4 Up to 2 Up to 2 28−32 until 3 Up to 1,5 the basis until 3 3.5−5.5

Additional doping with an entire complex of impurities in the form of tungsten, molybdenum, iron, manganese and a number of others perfectly complements the fundamental chromocobalt base and further enhances the important working qualities of the alloy.

Application of

A large assortment of various products from the cobalt alloy 6b makes it possible to find the most acceptable option for solving the production problem of almost any complexity. We supply pipes of various sections, sheets, profile products (flanges, fittings), wire, circle, strip. Requirements for the manufacture of such products are standardized by Gosstandart, which is a guarantee of high quality of finished products. Due to high performance and reliable performance of semi-finished products made from this unique alloy, they can be used in virtually any industrial area, regardless of the presence of harmful factors or temperature load. Most often semi-finished products of this type are used for the manufacture of pumping plants, bearings, medical and heat exchange equipment. There is the possibility of manufacturing structural elements for individual orders, in the absence of necessary parts in the standard series.
