HS111 Cobalt-based Stellite Welding Wire

Meets GB/T 29713 RCoCr-A
       YB/T 5092 H111
       AWS A5.9 RCoCr-A
       ISO 14343-B-RCoCr-A

Description: The HS111 Cobalt-based Overlay Weld Wire is a Co-Cr-W Overlay Alloy with low C and W content and excellent toughness. It can withstand impact under both cold and hot conditions with a low tendency to crack, and boasts excellent corrosion resistance, heat resistance, and wear resistance.

Application: Primarily used for applications requiring excellent wear and corrosion resistance at high temperatures, such as high-pressure valves, hot cutting blades, hot forging dies, etc.

Fusion Metal Chemical Composition (%)

Hardness of surfacing layer: HRC 40-45

Cautionary Notes:

1. Protective Gas: Pure Ar; Flow Rate: 9-14L/min at 100-200A current, 14-18L/min at 200-300A current.
Tungsten electrode extension length: 3~5mm; arc length: 1~3mm.
3. Wind speed is limited to ≤1.0m/s; it is recommended to use argon gas protection on the backside of the welding area.
4. In welding, the size of the welding line energy directly affects the mechanical properties and crack resistance of the weld metal, which should receive more attention.
5. Ensure the rust, moisture, oil stains, and dust from the welding areas are thoroughly removed.
The above suggestions are for reference only. The on-site conditions should be taken as the standard for specific operations. In case of necessity, perform a process evaluation first before determining the welding plan.

HS112 Cobalt-based Welding Wire

Meets GB/T 29713 RCoCr-B
       YB/T 5092 H112
       AWS A5.9 RCoCr-B
       ISO 14343-B-RCoCr-B

Description: The HS112 Cobalt-based Welding Wire has medium hardness in Co-Cr-W Stellite Alloys, better wear resistance than HS111, slightly lower ductility, and excellent corrosion, heat, and wear resistance. It maintains these properties at around 650°C high temperatures.

Application: Primarily used for high-temperature, high-pressure valves, internal combustion engine valves, high-pressure pump shaft sleeves and liners, hot rolling roller holes, etc. for surfacing
