BÖHLER CAT 430L Cb-IG is a high alloyed special TIG rod for stainless and acid-resistant steels. Typical work covers tanks, process installations, food and chemical industry equipment and structures in contact with water and steam.
Typical base materials are 1.4511, X3CrNb17, 1.4016, X6Cr17 and AISI 430. The rod suits root runs, thin walls and welds that need a smooth face, and you feed the filler into the pool by hand while the arc burns between the tungsten electrode and the weld.
- Classification EN ISO: 14343-A Z18 Nb L
- AWS classification: A5.9 / SFA-5.9 ER430(mod.)
- Shielding gas: I1
- Diameters: 1.6 mm
Keep the heat input down and do not hold the joint hot longer than you need to, the structure expands and pulls out of shape. Grind the tungsten tip along its axis and hold a short arc, otherwise the pool spreads. Protect the root when you weld from one side, an oxidised underside spoils the corrosion resistance.
