China Cobalt-Based No. 1 Welding Wire Cobalt-Based Casting Rod Stellite 1/ Ercocr-C Cobalt-Based Wear-Resistant Welding Wire, Find details about China HS113 Cobalt-Based Welding Wire, Wear Resistant Electrode Specification 3.2mm from Cobalt-Based No. 1 Welding Wire Cobalt-Based Casting Rod Stellite 1/ Ercocr-C Cobalt-Based Wear-Resistant Welding Wire
Description: S111(Stellite 6) is a widely used cobalt - based alloy surfacing wire.Moderate carbon and tungsten content, good toughness.In 800?1?70?1?Excellent corrosion resistance, oxidation resistance, impact resistance and metal-to-metal adhesion wear resistance in temperature range below 78C.The surfacing layer can be machined.
Application: It is used in the high temperature condition of wear resistance and corrosion resistance to maintain good performance.Such as automotive, internal combustion engine valves, high temperature and high pressure valves, thermal shear blade, bearing inner and outer rings, hot forging die welding.

Physical properties (approximation)
1. Oxygen-acetylene welding or tungsten argon arc welding (manual or automatic) can be used for surfacing.
2. Oxygen-acetylene welding shall be surfacing with carbonization flame, and the length of firework core and inner flame shall be maintained at 1:3.
3. The corners of the welding surface must be processed into rounded corners.And after removing the oxide, oil and other dirt on the surface of the base metal, the surfacing welding is carried out.
4. According to the type of the base metal and the size of the workpiece, the appropriate preheating temperature should be selected for preheating.
5. During surfacing, the base metal only needs to be heated to the state of "sweating" (wetting) before the welding wire drops can be added, and the base metal should not melt.Each surfacing layer can be remelted by carbonization flame on the surface of the welding layer. Check whether there are any defects such as pores, dents or insufficient surfacing. Once found, repair them by welding.
6. After surfacing, the workpiece should be immediately put into the dry and preheated sand tank or grass ash and cooled slowly to avoid cracks.
7. The surfacing layer shall be roughed first. If any defects are found, the workpiece shall be preheated again and the welding repair shall be carried out in accordance with the above steps.
The price that
Product Name: Cobalt Base No. 2 Welding Wire
Description: S112(Stellite 12) has a high content of carbon and tungsten in the continuous casting cobalt base wire, and has a medium hardness. Its wear resistance is better than that of Stellite 6, but its toughness is slightly worse.Hardfacing layer has good corrosion resistance, heat resistance and wear resistance, up to 800?0?The high temperature of 8C also preserves these properties.The surfacing layer can be machined.
Application: It is used for surfacing welding of high temperature and high pressure valves, internal combustion engine valves, cutting edge of chemical fiber scissors, shaft sleeve and inner sleeve of high pressure pump, wood sawtooth, hot rolling fine rolling pass roll, etc.
