Corthal® 65 is a C -, Cr-, Nb-, Mo-, V- and Tu- alloyed, selfshielded flux cored wire electrode, which forms extremely hard carbides.
This alloy is used for hardfacing against extremely mineral wear.
The deposit retains its wear resistance up to 650°C but the coating should be limited to two layers.
The welding wires are used for applications on parts such as sinter breaker, grill bars, screens and plates in hot sintering area, mixer blades, blast furnace bells, chutes and liners and other.
The hardness up to 20°C: 63-65 HRC
The hardness up to 400°C: 61 HRC
The hardness up to 600°C: <57 HRC
