HYDROSTAR BLENDS: HYDROGEN SHIELDING GASES & WELDING GAS MIXTURES
Our HydroStar ® shielding gas blends are primarily used for joining austenitic stainless steels with the GTAW process. Hydrogen increases heat input to the base materials while providing a reducing atmosphere to enhance weld cleanliness. Significant advantages in travel speed over pure argon can be attained. Find out more about the different blends we offer below.
| MIXTURE | USES | SDS |
| HydroStar H-2 | This blend is used for manual welding and is suitable for use with GTAW when welding 300 series austenitic stainless steels. It is also used as a back purge gas on stainless steel materials. | H-2 (H2-Ar mixtures, nonflammable) E-6750 (67.1KB)HydroStar |
| HydroStar H-5 | This blend is used for manual welding applications and is preferred on material thicknesses above 1/16 inch. It is also suitable for use with GTAW when welding 300 series austenitic stainless steels and as a back purge gas on stainless steel materials. | H-5, H-10, H-35 E-6218 (69.9KB)HydroStar |
| HydroStar H-10 | This blend is preferred for high-speed GTAW mechanized applications on austenitic stainless steel. | H-5, H-10, H-35 E-6218 (69.9KB)HydroStar |
| HydroStar H-35 | It is recommended as the plasma gas with plasma arc gauging when cutting aluminum and stainless steel, and when cut quality and face appearance are critical. | H-5, H-10, H-35 E-6218 (69.9KB)HydroStar |
| HydroStar PBSS | This blend is designed for all-position welding of austenitic stainless steels using pulsed spray transfer. Optimum weld quality and cleanliness is achieved at high levels of productivity. | PBSS E-6792 (69.9KB)HydroStar |
