What is E80C-Ni1?
E80C-Ni1 (UNS W21030) is a nominal 1 % nickel composite metal-cored electrode in the low-alloy flux-cored filler family, alloyed to improve notch toughness at sub-zero temperatures. It is used on low-alloy structural and pipeline steels for cold-service fabrication, depositing 510 MPa yield, 600 MPa tensile, 25 % elongation and about 205 HB (94 HRB). Heat input should be capped near 2.0 kJ/mm to protect −40 °C toughness, and the deposit corrodes like plain carbon steel, so priming or galvanizing is needed. E80C-Ni2 and E80C-Ni3 extend toughness to lower temperatures. E80C-Ni1 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). E80C-Ni1 has a yield strength of 510 MPa (74 ksi) and a tensile strength of 600 MPa (87 ksi) — stronger than 65% of steel grades. Elongation at break is 25% and the elastic modulus is 205 GPa (29.7 Msi).

Working with E80C-Ni1
Is E80C-Ni1 easy to machine?
Weld cap machines like a normalized low-alloy steel (~50 % of AISI 1212); expect harder, less uniform passes near the fusion line.
Can E80C-Ni1 be welded?
Run with 75–80 % Ar / balance CO₂ (or 100 % CO₂ with slightly lower toughness), DCEP, preheat per CE of the base steel and cap heat input around 2.0 kJ/mm to protect −40 °C toughness.
Can E80C-Ni1 be formed, bent or molded?
Not a formed product; keep interpass temperature ≤150–200 °C and reseal/redry spools to avoid moisture pickup and porosity.

What surface finishes work on E80C-Ni1?
Deposit rusts freely — grind/blast and prime or galvanize; the ~1 % Ni gives no meaningful bare-metal corrosion protection.

E80C-Ni1 — frequently asked
What is E80C-Ni1 used for?
E80C-Ni1 is typically used for low-temperature pipeline steel, cold region structural fabrication, offshore jacket structures and pressure vessel low-temperature service. In short: entry-level cold-service filler; 1 % Ni toughness boost; lowest-alloy Ni-series option.
What is the yield strength of E80C-Ni1?
E80C-Ni1 has a typical yield strength of 510 MPa (74 ksi) and a tensile strength of 600 MPa (87 ksi) — stronger than 65% of steel grades. Strength varies by condition: see the 2 listed tempers.
Is E80C-Ni1 easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 65% of steel grades). Weld cap machines like a normalized low-alloy steel (~50 % of AISI 1212); expect harder, less uniform passes near the fusion line.
Can E80C-Ni1 be welded?
Yes — weldability is rated excellent (88/100). Run with 75–80 % Ar / balance CO₂ (or 100 % CO₂ with slightly lower toughness), DCEP, preheat per CE of the base steel and cap heat input around 2.0 kJ/mm to protect −40 °C toughness.
What surface finishes work on E80C-Ni1?
Deposit rusts freely — grind/blast and prime or galvanize; the ~1 % Ni gives no meaningful bare-metal corrosion protection.
Can E80C-Ni1 be formed, bent or molded?
Not a formed product; keep interpass temperature ≤150–200 °C and reseal/redry spools to avoid moisture pickup and porosity.
What is the maximum service temperature of E80C-Ni1?
E80C-Ni1 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 E80C-Ni1-AW and E80C-Ni1 PWHT?
AW is the default condition — default classification condition per AWS A5.28 — use for cold-service structural welds where no PWHT is applied. PWHT: pick when the fabrication code requires stress relief — strength drops slightly, ductility and toughness improve. Yield strength is 510 MPa in AW versus 470 MPa in PWHT.
How much does E80C-Ni1 cost?
E80C-Ni1 is a standard-cost steel ($$), cheaper than about 71% 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.
