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 machined with cutting tools.
Gridur 300 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 recommended for the last 2-3 layers of the rail welding process.
