Abstract
9 percent nickel steel has been evaluated for use in a semimembrane LNG containment design. Fatigue and fracture toughness properties of 1/4 in. thick base plate and weldments have been determined at cryogenic temperatures. Results of rotating beam fatigue, stress intensity (Kc) and fatigue crack growth rate (da/dN versus ΔK) studies are presented. Data predict that 9 percent nickel steel, fabricated with the gas metal arc and shielded metal arc welding processes, may be successfully applied as the primary tank material for this LNG design.
