015H20N25G2B-ID (EP754-ID)

It is used more often for the production of pipe billet, which is later used for the production of pipes in the chemical and energy field, including the construction of nuclear power plants. Currently, steel of this brand is also well used in the construction of large buildings such as: airports, shopping complexes and other most important objects in everyday life.
