Annealing Gas Atmospheres

Gas atmospheres for annealing can range from nitrogen-based blends with hydrogen for carbon steels (to improve microstructure, surface appearance and reduce residual stresses), to 100% hydrogen (for stainless steels or for faster batch processing of carbon steel components). For vacuum annealing of reactive metals, we can provide argon or helium atmospheres. Our atmospheres can help you achieve improved and consistent part quality, reduced post-heat-treatment cleaning or pickling costs and reduced furnace maintenance.
