Hard Facing Electrodes
EH 528 HARD FACING ELECTRODE
• Heavy Abrasion Moderate Impact
• Non Machinable, Grind Only
• Chrome, Niobium Carbide Matrix
• Easy Strike and Restrike
• Relief Checks in Final Deposit
• Metal Recovery 180%
A basic type heavy coated high recovery electrode for depositing primary and eutectic Cr and Nb carbides in ­
austenitic matrix. Suitable for hardfacing of parts subjected to heavy abrasion with moderate impact. Service temperature is ­
maximum 450˚C. The typical transverse cracks occurring in such a hard metal is not suitable for applications where
impact and shock conditions prevail. Wear coefficient of one layer deposit is 0.5 % with Si O2. The weld metal is ­
machinable only by grinding. Metal recovery of 180%. Suitable to use in hardfacing of cement crushers, cement ­
presses and brick conveyor screws, mixer blades, press screws in the oil industry, bucket lips and teeth in earth moving ­
equipment. Possible to use with both DC and AC.

Approvals
AWS/ASME SFA 5.13 E Fe Cr- A2 • DIN 8555 E 10 UM 65 GRZ
A heavy coated, high recovery (235%) hardfacing electrode depositing evenly distributed Cr, B carbides in austenitic
stainless steel matrix. Suitable for hardfacing of parts subjected to heavy abrasion with moderate impact. Required ­
hardness and abrasion resistance can be obtained in the first layer even on low alloy steels. The hardfacing layers have
a very smooth surface and machinable only by grinding. Suitable to use in excavator teeth, leading edges of excavator
buckets, mixer blades, gravel pumps, conveyor worm-screws and conveyor belts. Possible to use with both DC and AC.
