Description

ER120S-1 deposits high-strength, very tough weld metal for critical applications. Originally developed for welding HY100 steels for military applications, it is also used for a variety of structural applications where tensile strength requirements exceed 100 ksi (690 MPa), and excellent toughness is required to temperatures as low as -60ºF (-51°C). 120S-1 can be welded in all positions. Recommended shielding gas is CO2 or Argon/O2 mix.
