What is E6011-AW?
E6011-AW is E6011 heat treated to AW — standard supplied/qualified condition: properties of the undiluted deposit in the as-welded state, no post-weld heat treatment. E6011-AW has a yield strength of 400 MPa (58 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 60% of steel grades. Elongation at break is 26% and the elastic modulus is 205 GPa (29.7 Msi). E6011-AW has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,460°C (2,660 °F).

Working with E6011-AW
Is E6011 easy to machine?
Deposit machines like mild steel but slag inclusions and hard HAZ zones dull tooling — grind the crown flat before finish cuts.
Can E6011 be welded?
Run AC or DCEP with a tight, whipped arc; deep penetration handles rust, paint and galvanizing residue, but keep hydrogen-sensitive or thick, restrained joints for low-hydrogen E7018 instead.
Can E6011 be formed, bent or molded?
Not a wrought product — deposits can be peened or lightly dressed, but avoid severe cold bending across as-welded beads.
What surface finishes work on E6011?
Heavy spatter and coarse ripple require grinding/wire-brushing; then prime and paint or galvanize since bare deposit rusts quickly.

E6011-AW — frequently asked
What is E6011-AW used for?
E6011-AW is typically used for maintenance welding, farm equipment repair and general steel fabrication. In short: runs on AC transformers; tolerates dirty, painted steel; not low-hydrogen.
What is the yield strength of E6011-AW?
E6011-AW has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 60% of steel grades. Strength varies by condition: see the 2 listed tempers.
Is E6011-AW easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Deposit machines like mild steel but slag inclusions and hard HAZ zones dull tooling — grind the crown flat before finish cuts.
Can E6011-AW be welded?
Yes — weldability is rated excellent (85/100). Run AC or DCEP with a tight, whipped arc; deep penetration handles rust, paint and galvanizing residue, but keep hydrogen-sensitive or thick, restrained joints for low-hydrogen E7018 instead.
What surface finishes work on E6011-AW?
Heavy spatter and coarse ripple require grinding/wire-brushing; then prime and paint or galvanize since bare deposit rusts quickly.
Can E6011-AW be formed, bent or molded?
Not a wrought product — deposits can be peened or lightly dressed, but avoid severe cold bending across as-welded beads.
What is the maximum service temperature of E6011-AW?
E6011-AW is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E6011-AW and E6011-SR?
AW is the default condition — standard supplied/qualified condition: properties of the undiluted deposit in the as-welded state, no post-weld heat treatment. SR: choose when code work (e.g. ASME/B31 piping) requires PWHT; strength drops slightly and ductility/toughness improve. Yield strength is 400 MPa in AW versus 360 MPa in SR.
