Hydrogen controlled basic type electrode for tough easily machinable welds.
Gridur 250B electrode is used for medium hardness hard facing with high resistance to abrasion both by sliding and rolling action. The tough weld metal can also withstand hard blows. Among other applications, Gridur 250B recommended for the last 2-3 layers of the rail welding process. The slag is easily removable and the weld metal can be machined with cutting tools.
