ESAB’s Cryo-Shield Ni9 flux-cored wire offers crack resistance

ESAB Welding & Cutting Products

ESAB Welding & Cutting Products has introduced Cryo-Shield Ni9, a nickel-chromium-molybdenum alloy flux-cored wire used for all-position welding of 9% Ni steel LNG fuel and storage tanks with 100% CO2 shielding gas. This modified 625-type wire offers crack resistance and mechanical properties that are similar to Hastelloy ENiMo-13 flux-cored wires, states the company. It carries approvals from the ABS, BV, DNV GL, KR, LR, and CCS classification societies.

The wire is available in 1.2 mm dia. and packaged on 300-mm wire baskets or plastic spools. Vacuum-seal foil packaging prevents moisture absorption. Typical as-welded mechanical properties are a yield strength of 440 MPa, tensile strength of 730 MPa, elongation of 44%, and an impact value of 65 J at -196 degrees C.
