Welding electrodes CCH-4
product.uv
- it is recommended to hold the electrode vertically to the part
- welding should be done with a very short arc and as little current as possible to prevent mixing with the base metal
- To obtain maximum hardness on low-carbon steels, a minimum of 3 layers should be applied
product.sv
- based metal can be tempered at 840-860°C, then hardened to 950-1000°C and cooled in oil or air
- only abrasive machining of the deposited metal
- abrasive wear resistance is very good, shock load resistance and corrosion resistance is satisfactory, heat resistance is good
Designed for cold welding of structures made of high-strength cast iron with ball graphite and gray cast iron with flake graphite, as well as connecting them to steel.
