Type
Solid stainless steel welding wire for Tig welding. (Type 29 9, 312, 1.4337)
classification
AWS
A 5.9: ER312
EN ISO
14343-A: W 29 9
W.Nr.
1.4337
Applications

Buffer layers before hardfacing, armor plate, exhaust systems, high, Manganese austenitic steel, heterogeneous welding, difficult to weld and unknown steels. Is suitable for wear resisting build-ups on clutches, gear wheels, shafts, etc. It is also suitable for repair welding of tools. For welding of unalloyed steels with limited weldability and low-alloyed steels of higher strength. Used as stress-relieved buffer layer when cladding cold and warm machine tools. For joining of high manganese and CrNiMn-steels and combinations of steels of different chemical composition or strength.

Properties

Scale resistance up to 1150ºC, crack and wear resistant, suitable for rebuilding wornout parts. Excelent corrosion resistance against high temperature liquid acids. Application temperature max. 300ºC. High resistance to hot cracking, good toughness and strength properties. The weld metal also work hardens.
