Hydrogen Generators for Metallurgy
High-purity on-site hydrogen generation for bright annealing, sintering, brazing, and heat treatment applications in metal processing and powder metallurgy.
Why Hydrogen in Metallurgy?
Hydrogen offers unique advantages in metallurgical processes, actively reducing metal oxides and creating superior protective atmospheres for heat treatment operations.
Active Oxide Reduction
Unlike inert gases, hydrogen actively reduces metal oxides on surfaces, producing ultra-bright, oxide-free finishes without mechanical or chemical post-processing.
Lower Processing Temperatures
Hydrogen's high thermal conductivity enables faster heating and cooling cycles, reducing processing temperatures by 50-100°C and saving energy costs.
Superior Surface Quality
Produces mirror-bright surfaces on stainless steel, copper, brass, and other metals, eliminating the need for pickling, polishing, or other finishing operations.
Enhanced Material Properties
Improves ductility, reduces brittleness, and enhances mechanical properties by preventing decarburization and maintaining precise carbon content during heat treatment.
Cost Efficiency
On-site generation eliminates cylinder rental, delivery fees, and handling costs. Lower processing temperatures reduce energy consumption by up to 30%.
Faster Processing
Superior heat transfer properties enable rapid heating and cooling cycles, increasing throughput and reducing cycle times by 20-40% compared to nitrogen atmospheres.
