SK 256-O high alloyed steels
Classifications open arc metal cored wire
DIN 8555
MF 10-GF-65-G
Characteristics
High Chromium carbide alloy designed to resist high stress grinding abrasion with low
impact. The deposits will readily show stress relief cracks.
Microstructure: Primary Chromium carbides (70 %) and eutectic carbides in an
austenitic matrix
Machinability: Grinding only
Oxy-acetylene cutting: Cannot be flame cut
Deposit thickness: 10 to 12 mm maximum in 2 to 3 layers
Field of use
Coal pulverizing rollers, mining and earthmoving equipment, sand dredge parts, drag line
components, etc.
