CHARACTERISTICS

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.


APPLICATION

Sinter crusher, sinter grates, hot screening units, blast furnace hoppers and throats, ovens, extractor fans etc..
