HYUNDAI ELECTRODE 11018-M 2.6MM

Electrode 11018-M – High-Tensile Low-Hydrogen Stick Electrode (HSLA Steels)

The 11018-M electrode is a premium high-tensile, low-hydrogen MMA (stick) electrode engineered for critical welding applications involving high-strength low-alloy (HSLA) steels. Designed to meet demanding structural and safety requirements, this electrode delivers weld deposits with a minimum tensile strength of 110,000 psi, making it suitable for high-load, safety-critical fabrication and repair work.

Key Applications

• Military & Defence
  Ideal for welding armour plate and high-yield steels including HY-80, HY-90 and HY-100, where strength and toughness are essential.

• Industrial Infrastructure
  Commonly used in bridge fabrication, offshore structures, and power generation facilities requiring high structural integrity.

• Heavy Machinery & Equipment
  Suitable for the manufacture and repair of crane booms, excavator components, trailer frames, and heavy earthmoving equipment.

• High-Strength & Quenched / Tempered Steels
  Recommended for steels such as ASTM A514 (T-1), A517, and high-strength plate grades including Weldox 700.

• Pressure Vessels & Penstocks
  Used in the fabrication of heavy boilers, penstocks and pressure vessels where high radiographic quality is mandatory.

Performance Characteristics

• Low-Hydrogen Iron Powder Coating (E11018)
  Minimises hydrogen-induced cracking and supports sound weld metal integrity in high-strength steels.

• Excellent Impact Toughness
  Delivers strong ductility and notch toughness at low temperatures, typically down to –51°C to –60°C, depending on procedure.

• X-Ray / Radiographic Quality Welds
  Produces clean, defect-free weld deposits suitable for critical joints requiring non-destructive testing.

• All-Position Welding
  Approved for all positions, with particularly smooth performance in flat (downhand) and horizontal applications.

Handling, Storage & Usage Requirements

• Moisture Control is Critical
  Electrodes must be stored in hermetically sealed containers or held in an electrode oven at 120–150°C to maintain low hydrogen levels.

• Re-Drying (If Exposed)
  If exposed to atmospheric moisture, re-bake at 350–400°C for approximately 1 hour prior to use.

• Welding Procedure Control
  Preheat and interpass temperature control are typically required, depending on steel grade, thickness and joint design, to ensure weld integrity.

Why Choose 11018-M from QWS?

The 11018-M electrode is the trusted choice for welders working in high-risk, high-load and regulated environments where weld failure is not an option. When combined with correct storage and welding procedures, it delivers exceptional strength, toughness and reliability across the most demanding applications.
