Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Post-weld heat treated | Use when the fabrication code mandates stress relief; residual stress and hardness drop but so does tensile strength — verify the joint still meets the 110 ksi design basis. | 670 | 760 | 21 | 20 HRC | 7.6 % IACS |
AW-CO₂ | Pick when shop gas is straight CO₂; deeper penetration and lower cost but slightly lower toughness and higher spatter than Ar-mix. | 710 | 800 | 18 | 23 HRC | 7.5 % IACS |
AWDefault As-welded deposit | Standard classification condition — deposit used as welded on Q&T high-strength steels; best combination of 110 ksi strength and low-temperature toughness. | 720 | 810 | 19 | 24 HRC | 7.5 % IACS |
What is E110C-K3?
E110C-K3 is a Ni-Cr-Mo composite flux-cored/metal-cored electrode giving roughly 110 ksi tensile weld metal: 810 MPa tensile, 720 MPa yield, 19 % elongation and about 250 HB (24 HRC) as welded, with service to 400 °C. It is chosen for the higher-strength quenched-and-tempered steels such as HY-100 in ship, pressure and heavy-structure work, and is supplied as spooled tubular wire for gas-shielded welding (AW, AW-CO2 and PWHT conditions on file). It demands strict low-hydrogen practice, preheat and interpass and heat-input limits to protect HAZ toughness; where base-metal strength is lower, E100C-K3 is the easier choice. E110C-K3 has a density of 7.8 g/cm³ (0.282 lb/in³), lighter than 87% of steel grades. It melts at 1,460°C (2,660 °F). E110C-K3 has a yield strength of 720 MPa (104 ksi) and a tensile strength of 810 MPa (117 ksi) — stronger than 82% of steel grades. Elongation at break is 19% and the elastic modulus is 205 GPa (29.7 Msi).

Working with E110C-K3
Is E110C-K3 easy to machine?
As-welded deposit is ~24 HRC; machine with carbide at moderate speed or stress-relieve first to ease cutting and reduce distortion.
Can E110C-K3 be welded?
DCEP, gas-shielded metal-cored (75-80 % Ar / bal CO₂ preferred); keep hydrogen low, preheat/interpass per the Q&T base metal (typically 50–150 °C, interpass ≤200 °C) and cap heat input to protect HAZ toughness.
Can E110C-K3 be formed, bent or molded?
Not a wrought product — the wire is drawn and formed by the maker; the deposit itself has limited cold formability at 760 MPa yield.

What surface finishes work on E110C-K3?
Grind/blast to remove silicon islands and slag film, then zinc-rich primer or paint; no anodizing, avoid electroplating without bake-out to prevent hydrogen embrittlement.

E110C-K3 — frequently asked
What is E110C-K3 used for?
E110C-K3 is typically used for HY-100 steel welding, high-strength ship hull structures, pressure vessel repair and heavy crane structures. In short: 110 ksi weld deposit; HY-100 matching filler; highest-strength K3 wire.
What is the yield strength of E110C-K3?
E110C-K3 has a typical yield strength of 720 MPa (104 ksi) and a tensile strength of 810 MPa (117 ksi) — stronger than 82% of steel grades. Strength varies by condition: see the 3 listed tempers.
Is E110C-K3 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 77% of steel grades). As-welded deposit is ~24 HRC; machine with carbide at moderate speed or stress-relieve first to ease cutting and reduce distortion.
Can E110C-K3 be welded?
Yes — weldability is rated excellent (90/100). DCEP, gas-shielded metal-cored (75-80 % Ar / bal CO₂ preferred); keep hydrogen low, preheat/interpass per the Q&T base metal (typically 50–150 °C, interpass ≤200 °C) and cap heat input to protect HAZ toughness.

Not a wrought product — the wire is drawn and formed by the maker; the deposit itself has limited cold formability at 760 MPa yield.
What is the maximum service temperature of E110C-K3?
E110C-K3 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 E110C-K3-AW and E110C-K3 PWHT?
AW is the default condition — standard classification condition — deposit used as welded on Q&T high-strength steels; best combination of 110 ksi strength and low-temperature toughness. PWHT: use when the fabrication code mandates stress relief; residual stress and hardness drop but so does tensile strength — verify the joint still meets the 110 ksi design basis. Yield strength is 720 MPa in AW versus 670 MPa in PWHT.
How much does E110C-K3 cost?
E110C-K3 is a premium-cost steel ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
