What is E110C-K4?
E110C-K4 is a Ni-Cr-Mo alloyed composite (flux/metal-cored) electrode from the AWS low-alloy steel filler family, depositing roughly 110 ksi weld metal — 745 MPa yield, 830 MPa tensile, 19 % elongation. Engineers select it for joining and repairing quenched-and-tempered high-strength plate where low-temperature notch toughness is required; it is supplied as spooled cored wire for gas-shielded GMAW/FCAW in as-welded (AW) or PWHT condition. The deposit runs about 255 HB (25 HRC), is limited to roughly 400 °C service, rusts like carbon steel and demands strict low-hydrogen practice. E120C-K4 is the next strength step in the same family. E110C-K4 has a density of 7.83 g/cm³ (0.283 lb/in³), lighter than 80% of steel grades. It melts at 1,450°C (2,642 °F). E110C-K4 has a yield strength of 745 MPa (108 ksi) and a tensile strength of 830 MPa (120 ksi) — stronger than 83% of steel grades. Elongation at break is 19% and the elastic modulus is 205 GPa (29.7 Msi).

Working with E110C-K4
Is E110C-K4 easy to machine?
Deposit at ~25 HRC machines like Q&T low-alloy steel — use carbide tooling, moderate speeds; grind flush before NDT.
Can E110C-K4 be welded?
Spray-transfer GMAW with 75-80 % Ar/balance CO₂ (or 100 % CO₂ at reduced toughness); keep heat input ≤2.0 kJ/mm, interpass ≤150 °C, preheat per Q&T base metal to avoid hydrogen cracking; keep wire dry and packaging sealed.
Can E110C-K4 be formed, bent or molded?
Not a wrought product — deposit geometry set by joint design; avoid cold straightening of high-strength weldments.

E110C-K4 — frequently asked
What is E110C-K4 used for?
E110C-K4 is typically used for high-strength offshore structures, military vehicle armor, heavy mining equipment and quenched and tempered steel repair. In short: 110 ksi low-alloy deposit; improved low-temperature toughness; matches Q&T plate strength.
What is the yield strength of E110C-K4?
E110C-K4 has a typical yield strength of 745 MPa (108 ksi) and a tensile strength of 830 MPa (120 ksi) — stronger than 83% of steel grades. Strength varies by condition: see the 2 listed tempers.
Is E110C-K4 easy to machine?
Not especially — machinability is rated fair (42/100, worse than 73% of steel grades). Deposit at ~25 HRC machines like Q&T low-alloy steel — use carbide tooling, moderate speeds; grind flush before NDT.
Can E110C-K4 be welded?
Yes — weldability is rated excellent (85/100). Spray-transfer GMAW with 75-80 % Ar/balance CO₂ (or 100 % CO₂ at reduced toughness); keep heat input ≤2.0 kJ/mm, interpass ≤150 °C, preheat per Q&T base metal to avoid hydrogen cracking; keep wire dry and packaging sealed.

Can E110C-K4 be formed, bent or molded?
Not a wrought product — deposit geometry set by joint design; avoid cold straightening of high-strength weldments.
What is the maximum service temperature of E110C-K4?
E110C-K4 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-K4-AW and E110C-K4 PWHT?
AW is the default condition — standard classification condition for E110C-K4; use for high-strength steel joints where PWHT is not applied. PWHT: choose when the fabrication code requires stress relief; expect a modest drop in strength and hardness with slightly better ductility. Yield strength is 745 MPa in AW versus 695 MPa in PWHT.
