Title:
COMBUSTOR LINER FOR GAS TURBINE, AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH11217644
Kind Code:
A
Abstract:
To provide a combustor liner for gas turbine, superior in high temperature strength to a combustor liner made of conventional refined and cast alloy and hardly causing structural change attendant on aging, and its production, by applying casting treatment and then applying hot plastic working such as forging treatment.
A combustor liner 14 for gas turbine has a composition consisting of, by weight, 18.0-25.0% Cr, 17.0-23.0% Co, ≤10.0% of at least either of Mo and W, 0.01-3.0% Al, ≤2.0% Ti, ≤2.0% Ta, ≤2.0% Nb, ≤0.5% Hf, ≤0.5% C, and the balance Ni with inevitable impurities.
