- Hardfacing wire LZ632
LZ632 is a highly C- Cr- Mo- Nb- W- V- alloyed open arc flux-cored wire, which forms extremely complex hard carbides. This is used for hardfacing to extremely strong abrasive mineral wear. The deposit retains its wear resistance up to 800°C. The structure consists of primarily and eutectic solidifying Cr- carbides plus Nb- Mo- W- V- carbides. The hardness reduction at a temperature of 400°C is approximately 4% and at 700°C approximately 10 %. This wire is recommended for use in sintering plants, augers and blast furnace bells, The properties are reached in only three layers and relief checking is normal.
