CLASSIFICATIONS: E101T1-G per AWS/ANSI A5.29, SFA 5.29.
Select 101 SR is a low alloy steel, all position, flux cored electrode designed for use with external gas shielding. It is intended for single and multiple pass welding of quenched and tempered steels that require a postweld stress relief. It also produces excellent high strength properties in the as-welded condition. The preferred shielding gas for Select 101 SR is 75-80% argon – balance carbon dioxide; the use of 100 percent carbon dioxide should be avoided. Recommended gas flow rates are 35-50 cfh, and welding grade argon - carbon dioxide should be used with a dew point of at least -40° F.
APPLICATIONS: Select 101 SR is designed to weld oil field components that require a postweld stress relief*. It is an excellent choice for welding quenched and tempered steels such as 4130, 8630 and similar types. Weld metal nickel contents of less than 1.0% meet NACE requirements. Select 101 SR may also be used to weld high strength, low alloy steels where 100 ksi minimum tensile strength and excellent toughness are required in the as welded condition.
* Select 101 SR is designed for use where the weldment is to be postweld stress relieved. It is not designed for postweld quench and temper treatments. Select 4130LN should be used if the weldment is to receive a postweld quench and temper.
CHARACTERISTICS: Select 101 SR is a premium low alloy steel, flux cored electrode, with a rutile based slag system. This product operates in a spray-like transfer, with low spatter and good welder appeal. The fast freezing slag facilitates welding in all positions. There is moderate slag volume, with complete coverage, and easy removal.

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.
