ATOM ARC 10018
Atom Arc 10018 is an all-position low hydrogen electrode used primarily for applications requiring weld joints of at least 100 ksi (690 MPa) tensile strength, good ductility and crack resistance.
Features
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 -60ºF (-51ºC) is possible with this electrode. Atom Arc 10018 can be used to weld HY-80 and T-1 steel.
