Low Alloy Wire

UltraCore® E81T-1Ni1MJ H4 75% Argon / An extension of our superior line of carbon steel UltraCore®
81Ni1A75-H 25% CO2 products, 81Ni1A75-H is designed for high strength, low-alloy
19-20

applications using 75% Argon / 25% CO2. The use of mixed
shielding gas stabilizes arc characteristics, reduces spatter
levels, and washes out the weld bead for a flat appearance.
These electrodes exhibit robust impact properties, even with a
notch offset of 2.5 mm from weld centerline, as well as superior
crack resistance, due to low diffusible hydrogen levels (4mL/100
grams of weld deposit max). This electrode is ideally suited to
replace E8018-C3 stick electrodes for added efficiency and
increased productivity in bridge fabrication, offshore work, or
structural fabrication.

UltraCore® E81T-1Ni1CJ H4 100% CO2 An extension of our superior line of carbon steel UltraCore ®
81Ni1C-H products, 81Ni1C-H is designed for high strength, low-alloy
21-22

applications using 100% CO2. These electrodes exhibit robust
impact properties, even with a notch offset of 2.5 mm from weld
centerline, as well as superior crack resistance, due to low
diffusible hydrogen levels (4mL/100 grams of weld deposit max).
This electrode is ideally suited to replace E8018-C3 stick
electrodes for added efficiency and increased productivity in
bridge fabrication, offshore work, or structural fabrication.

UltraCore® E81T-1Ni2MJ H4 75% Argon / Look to UltraCore ® 81Ni2A75-H for high strength, low alloy
81Ni2A75-H 25% CO2 applications where productivity and consistency are a must in
23-24

75% Argon / 25% CO2 applications. The mixed shielding gas
stabilizes arc characteristics, reduces spatter levels, and
washes out of the weld bead for a flat appearance. This welding
wire exhibits superior crack resistance due to low diffusible
hydrogen levels (4 mL/100 grams of weld deposit max). Even
with a notch offset of 2.5 mm from weld centerline, this wire
displays robust impact properties. Whether your application is
mining, offshore, or fabrication, UltraCore® 81Ni2A75-H is the
premier low alloy welding wire.

UltraCore® E81T-1Ni2CJ H4 100% CO2 To meet the most demanding requirements in high strength, low
81Ni2C-H alloy applications, UltraCore ® 81Ni2C-H is an outstanding
25-26

performer. This 100% CO 2 welding wire exhibits robust low
temperature impact properties, even with a notch offset of 2.5 mm
from weld centerline, while still maintaining H4 diffusible hydrogen
levels. Regardless of whether you are welding in mining, offshore,
or fabrication applications, UltraCore® 81Ni2C-H is a preferred
product for both consistency and productivity.

UltraCore 81Ni1A75-H
®

Low Alloy Wire
(AWS E81T-1Ni1MJ H4)
An extension of our superior line of carbon steel UltraCore® products, 81Ni1A75-H is
designed for high strength, low-alloy applications using 75% Argon / 25% CO2. The use
of mixed shielding gas stabilizes arc characteristics, reduces spatter levels, and washes
out the weld bead for a flat appearance. These electrodes exhibit robust impact
properties, even with a notch offset of 2.5 mm from weld centerline, as well as superior
crack resistance, due to low diffusible hydrogen levels (4mL/100 grams of weld deposit
max). This electrode is ideally suited to replace E8018-C3 stick electrodes for added
efficiency and increased productivity in bridge fabrication, offshore work, or structural
fabrication.

UltraCore 81Ni2A75-H
®

Low Alloy Wire
(AWS E81T-1Ni2MJ H4)
Look to UltraCore® 81Ni2A75-H for high strength, low alloy applications where
productivity and consistency are a must in 75% Argon / 25% CO2 applications.
The mixed shielding gas stabilizes arc characteristics, reduces spatter levels, and
washes out of the weld bead for a flat appearance. This welding wire exhibits
superior crack resistance due to low diffusible hydrogen levels (4 mL/100 grams of
weld deposit max). Even with a notch offset of 2.5 mm from weld centerline, this
wire displays robust impact properties. Whether your application is mining,
offshore, or fabrication, UltraCore® 81Ni2A75-H is the premier low alloy welding
wire.

2) What benefit is gained by using an E71T-12 instead of
an E71T-9, or E71T-1?
The main benefit is the upper limit on tensile strength. This reduces weld cracking
tendencies and reduces hardness. These products meet the lower manganese
requirements of the A-1 analysis group in the ASME Boiler and Pressure Vessel
Code, Section IX.

3) Who should use an E71T-12 product?
Generally speaking, anyone who is using an E71T-1 product should use an E71T-12
product. The welding characteristics of the products are similar and the E71T-12
mechanical properties, chemical composition, and impact requirements meet the
E71T-1 requirement. The E71T-12 classification is a more stringent specification.
Lincoln E71T-12s are tri-classified, so that you may be able to avoid procedure
qualification if a customer has qualified with an E71T-1 or E71T-9, but be sure to
verify the qualifications you need before the job starts. An E71T-12 product also
delivers better impact toughness for low temperature or fracture critical applications.

4) What industries typically use E71T-12 products?
Mainly pressure vessel, offshore, and shipbuilders use E71T-12 products, but bridge
and heavy equipment fabricators use them as well.

5) Do the industries that use E71T-12s have other requirements that
E71T-12 electrodes do not automatically meet?
Yes, in many cases they do have additional requirements. The two most common are
impact toughness properties and hydrogen levels. In many cases diffusible hydrogen
requirements for E71T-12s are below 8mL/100g. Customers often require toughness
properties that exceed 20 ft•lbf @-20˚F. UltraCore® 712A80, 712C and UltraCore®
712A80-H produce weld metal that exceed this requirement. UltraCore® 712A80-H
produces hydrogen levels below 4mL per 100g of weld metal.

NOTES

T E S T R E S U LT S
Test results for mechanical properties, deposit or electrode composition and diffusible hydrogen levels were obtained from a weld produced and tested according to prescribed
standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not
limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other
appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

C U S T O M E R A S S I S TA N C E P O L I C Y

inquiries to the best of their ability based on information provided to them by the customers and the knowledge they may have concerning the application. Our employees, however, are not
