CLASSIFICATIONS: E80T5-B2C per AWS A5.29, ASME SFA 5.29
Select 85-B2 is intended for single and multiple pass welding of
certain chromium-molybdenum steels, plate and pipe requiring 1 1/4%
chrome and 1/2% molybdenum in the weld deposit. The
basic slag limits welding to horizontal fillets and the flat position.
APPLICATIONS: Select 85-B2 is a good choice for welding steels
such as ASTM A387 Gr 11 plate and A335 Gr P11 pipe. These steels
are used in high temperature applications requiring creep resistance.
The basic slag imparts better CVN toughness than rutile slag electrodes
when welding these steels, which are used in the construction of
boilers, heat exchangers and pressure vessels.
DIAMETERS: 1/16", 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Excellent mechanical properties with basic slag.
Better CVN toughness properties than rutile-slag electrodes.

Notice: The results reported are based upon testing of the product under controlled laboratory conditions in accordance with American Welding Society Standards. Actual use of the product may produce different results due to varying conditions. An example of such conditions would be electrode size, plate chemistry, environment, weldment design, fabrication methods, welding procedure and service requirements. Thus the results are not guarantees for use in the field. The manufacturer disclaims any warranty of merchantability or fitness for any particular purpose with respect to its products.
