HARDFACING

GRIDUR 300

Classification :

DIN 8555 E 1-UM-300

Charecteristics :

Hydrogen controlled basic type electrode. The tough weld metal can also withstand hard blows. The slag is easily removable and the weld metal can be machned with cutting tools.

Typical Application :

This electrode is used for medium hardness hard facings with high resistance to abrasion both by sliding and rolling action. Among other applications, Gridur 300 is recommentded for the last 2-3 layers of the rail welding process.
