INOXLINE HE3H1 50L

The quality: Inoxline He3H1 is a triple gas mixture of (Ar = 95,5%, He = 3%, H₂ = 1,5 %),  R1 - ArHeH - 3/1,5 in according to EN ISO 14175.  The pressure of gas cylinder is 20 Mpa (200 bar) at the T= +15°C.
Solutions: We offer the cylinders of Inoxline He3H1 for rent (NOT for sell). It is an inert, and non-toxic mixture, widely used in TIG welding for austenitic stainless steels only (like 304, 316, etc.)
Application: Inoxline He3H1 is used in industry as a special purpose welding mixture for austenitic stainless steels allowing to obtain high-quality welds. Used in tank, pipe, equipment welding in food, beverage, chemical and pharmaceutical industries. Welding gas mixtures containing argon, helium, and hydrogen (e.g., Ar+He+ H₂) have several advantages over universal welding argon (Ar). The addition of hydrogen and helium allows for deeper penetration and a cleaner, more attractive weld seam.
Interesting information Even a small addition (1–2%) of hydrogen to the welding gas mixture can significantly increase welding speed at the same machine settings, due to hydrogen’s higher thermal conductivity compared to argon.
Hydrogen may only be added to mixtures used for welding austenitic stainless steels (such as 304 or 316), as these are the only steels resistant to hydrogen-induced cracking.
