Metal & Steel processing requires precise, oxygen-controlled atmospheres for annealing, sintering, and heat treatment. Nuberg Gas Plant Division supplies an on-site nitrogen gas plant for the steel industry, paired with hydrogen generation, replacing cylinder dependency with the reducing atmosphere these processes require.
Hydrogen functions as a reducing agent in metallic ore processing and is combined with nitrogen to create the reducing atmosphere used in heat treatment, annealing of stainless steel and magnetic steel alloys, sintering, copper brazing, and welding. Plant selection depends on hydrogen tolerance: the Dx-Model for applications requiring hydrogen at or below 0.4%, and the Cu-DX Model where hydrogen must be nil. Both plants deliver nitrogen purity from 99.999% to 99.9999%, with a dew point of -70°C.
Nitrogen-hydrogen atmosphere controls oxidation inside the annealing furnace during steel heat treatment cycles
Protective atmosphere prevents surface oxidation before and during coating.
Hydrogen atmosphere enables oxide-free copper brazing joints.
Reducing atmosphere supports metal powder consolidation without contamination.
Nitrogen assist gas prevents oxidation at the cut edge.
With more than 1,200 customized gas plants engineered since 1996, metal and steel processing is one of our core applications. The choice between the Dx-Model and Cu-DX Model comes down to how much hydrogen each process can tolerate.
From sourcing to delivery, we ensure premium quality and reliability at every step.
Let’s build a strong business relationship together.
