Typical Chemical Composition of E71T-1C Weld Metal

The weld metal chemistry is carefully controlled to achieve stable arc performance and high-quality weld deposits. Typical undiluted weld metal composition includes approximately 0.06% Carbon, 1.40% Manganese, and 0.40% Silicon. This balanced composition supports good penetration, controlled slag formation, and excellent mechanical properties.

Mechanical Properties of E71T-1C Flux Cored Welding Wire

The E71T-1C welding wire produces weld metal with strong and dependable mechanical performance. Typical ultimate tensile strength is around 570 MPa, with a specified minimum of 490 MPa. Yield strength at 0.2% offset typically reaches 480 MPa, exceeding the minimum requirement of 390 MPa. Elongation values are typically around 26%, with impact toughness values reaching up to 60 Joules, meeting and surpassing standard specifications.

These properties make the wire suitable for load-bearing structures and dynamic service conditions.
