CastoTig 45412 W

CastoWig 45412 W, Ø 3.2mm, 5.0 kg

The heat-resistant cobalt hard alloy is resistant to abrasion, pressure and moderate impact stress at high temperatures. Corrosion resistant. Very high resistance to erosion and cavitation. Heat resistant up to 900 °C. Low coefficient of friction with metallic sliding friction. Insensitive to adhesive wear (even in the absence of lubrication).

Technical data
DIN EN 14700: S Co2
AWS A5.13: RCoCr-B
Hardness: 45 - 50 HRC

Applications
For build-up welding of unalloyed, low-alloy and high-alloy steels, tool steels and corresponding cast steels as well as nickel-based alloys.

Typical applications are
Hot work tools with low thermal shock stress such as dies, hot shear blades, hot trimming tools and hot piercing mandrels as well as workpieces subject to high thermal stress such as running or sealing surfaces on gas, water, steam and acid fittings, shaft seals, valve seats and cones of combustion engines and crushing machines for chemical products.

Processing instructions
Remove cracked or damaged material. Clean welding areas. During welding, adjust heat conduction to the component, its material and dimensions. Preheat to at least 450 °C for TIG welding. For gas welding, reduce the flame.
Ensure a continuous supply of filler material. Do not remove the molten rod end from the shielding gas flow. Do not fall below the preheating temperature during welding. Allow to cool in still air.

Welding positions: all, except PG (f)
