E6011 Rod

Chemical Composition & Mechanical Properties

Chemical Composition (Deposited Metal)

Carbon (C): ≤0.12% (typical test value: 0.06-0.08%), ensuring weld toughness and crack resistance.

Manganese (Mn): 0.3-0.9%, enhances weld strength and inhibits hot cracking.

Sulfur (S) & Phosphorus (P): Both ≤0.035%, impurities are strictly controlled to guarantee welding quality.

Mechanical Properties

Tensile Strength: ≥420 MPa (approx. 60 ksi), typical value: 480-540 MPa.

Yield Strength: ≥330 MPa, actual test value: 410-445 MPa, meeting the needs of medium-strength structural applications.

Elongation: ≥22% (δ5), the weld has good ductility and can withstand certain deformation.

Impact Toughness: ≥27 J at -30℃; some products reach over 50 J at 0℃, suitable for low-temperature environments.
