What Thermanit 21/10 N TIG rod is used for

Thermanit 21/10 N is a high alloyed austenitic stainless TIG rod. It works on pressure vessels, pipework and austenitic steel structures where corrosion resistance matters.

You feed the filler into the pool by hand while the arc burns between the tungsten electrode and the weld. The deposit has an austenitic structure that resists corrosion.

  • Classification EN ISO: 14343-A W 21 10 N
  • Shielding gas: I1
  • Diameters: 1.5 / 1.6 / 2.0 / 2.4 / 3.2 mm

Keep the heat input down and do not hold the joint hot longer than you need to, austenite expands strongly and pulls the structure out of shape. Protect the root when you weld from one side, an oxidised underside spoils the corrosion resistance. Keep the rod inside the gas shield even after you lift it from the pool, a cold oxidised end will contaminate the next drop. Thinner diameters suit root runs and thin sheet, thicker ones suit filling.
