ER90S-B3

 

ER90S-B3 is used to weld 2¼% Cr - 1% Mo steels used for high temperature, high pressure piping and pressure vessels. It is also used for joining carbon steel and Cr-Mo alloys. Careful control of preheat, interpass temperatures, and postweld heat treatment is essential to prevent cracking. When using 90S-B3 in the as-welded condition special care is required due to the higher strength levels. It can be used in all positions. Recommended shielding gas for GMAW is Argon/1-5% O2.

ER120S-1

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.

RG-45

RG-45 is a copper coated gas welding rod that is used for welding ordinary low carbon steel up to 1/4” thick. RG-45 produces ductile porosity free welds. It is recommended where ductility and machinability are most important. This rod is excellent for the welding of steel sheets, plates, pipes, castings and structural shapes where the minimum tensile strength requirement does not exceed 45,000 psi.

RG-60

RG-60 is used to produce high tensile strength quality welds on low carbon and low alloy steels. The high silicon and manganese composition removes impurities from the molten metal thereby eliminating the need for flux. RG-60 is also used for the oxyfuel gas welding of carbon steels, where the minimum tensile strength requirement does not exceed 60,000 psi.
