Cobalt hard alloy for wear protection
CastoWig 45406 W
The cobalt hard alloy is resistant to high temperatures and thermal shocks. Scale-resistant up to 1,200 °C. Withstands wear and impact stress. Good resistance to erosion and cavitation. Low coefficient of friction with metallic sliding friction. Insensitive to adhesive wear (even in the absence of lubrication). Corrosion-resistant to moist chlorine gas, diluted hydrochloric, sulphuric and acetic acid, salt solutions, seawater and hot gases containing sulphur.
Technical data
DIN EN 14700: S Co2
AWS A5.13: RCoCr-A
Hardness: 35 - 39 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
Components subject to heavy wear such as slide rails, extruder screws, sealing surfaces of fittings, valve seats in combustion engines, running surfaces of shaft seals, bearing points and grinding tools as well as hot working tools such as dies, hot shear blades, hot trimming tools, hot hole mandrels, dies and tips of stripper pliers.
Processing instructions
Remove cracked or damaged material. Clean welding areas. During welding, adjust the heat input 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)
Type of current: = (-)
