Hydrogen controlled basic type electrode for tough easily machinable welds.
WELD METAL ANALYSIS (RANGE) %
• 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.
