ATOM ARC LOW HYDROGEN LOW ALLOY ELECTRODES ATOM ARC 10018 FEATURES AWS A5.5: E10018MH4R TYPICAL MECHANICAL PROPERTIES Atom Arc 10018 electrodes are used primarily for applications which require weld joints of at least 100 ksi (690 MPa) tensile strength, good ductility and crack resistance. Good notch toughness at temperatures as low as -60°F (-51°C) is possible with this electrode. Atom Arc 10018 can be used to weld HY-80 and T-1 steel.
