E8018-B2 is an AWS A5.5 low-alloy low-hydrogen SMAW electrode with 80 ksi minimum tensile and a 1.25 Cr / 0.5 Mo alloy composition for elevated-temperature service. It is the standard for welding 1.25 Cr-0.5 Mo (P11) piping and pressure vessels in power generation, refinery, and petrochemical service. Runs DC+ or AC in all positions; PWHT (post-weld heat treatment) is typically required for code work.
Is this the same electrode as the parent Lincoln Excalibur 8018-B2 MR grade, just in a different package?
Yes. SKU ED032878 is the same AWS A5.5/A5.5M E8018-B2 classification as every other size in the Lincoln Excalibur 8018-B2 MR family. The only difference is diameter (3/32 in) and package format (3 x 8 lb easy-open cans). Polarity, position, and tensile properties are identical to the parent grade.
How many rods are in this 3 x 8 lb easy-open cans?
Approximately ~75 per 8 lb container (~225 total). Exact count varies with manufacturing tolerance but a 3 x 8 lb easy-open cans of 3/32 in Lincoln Excalibur 8018-B2 MR typically contains in this range.
What is the shelf life if I do not use them all?
Sealed cans have an indefinite shelf life when stored unopened in a dry environment. Once opened, low-hydrogen rods exposed beyond 4 hours of atmospheric humidity should be rebaked at 500-800 F for 1-2 hours or stored in a heated rod oven at 250-300 F to restore full code performance.
What diameter should I use for common applications?
3/32 in is well-suited for root passes, thin material, and out-of-position work. Heavier base metal and higher deposition typically calls for one diameter up; thinner sheet and root passes go one diameter down. See the parent grade page for full diameter-to-amperage guidance.
Can I mix this size with other diameters on the same job?
Yes, provided your procedure qualification (WPS) covers the diameter range. Many shops use one diameter for root, one for fill, and one for cap. All sizes within Lincoln Excalibur 8018-B2 MR share identical mechanical properties (AWS A5.5/A5.5M E8018-B2) so weld metal chemistry is consistent across passes.
Do I need to rebake these after the can is opened?
Yes for code-quality work. Per AWS D1.1 and most pressure-vessel codes, low-hydrogen electrodes exposed to atmosphere beyond 4 hours must be rebaked at 500-800 F for 1-2 hours or stored in a heated rod oven at 250-300 F to restore full code performance.
Does this size require a special holder or stinger?
Use an electrode holder rated for the amperage range above (70-110 A). Most general-purpose stinger holders (e.g. 300-500 A class) handle 3/32 in Lincoln Excalibur 8018-B2 MR without issue. For sustained high-amperage runs on larger diameters, a 500 A or higher holder is recommended.
Is this Buy America compliant?
This specific SKU is not the Buy America variant. Lincoln Excalibur 8018-B2 MR may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
