没有此类产品
产品描述
A nickel-iron-cobalt alloy with additions of niobium and titanium for precipitation hardening. It has the low coefficient of expansion and high strength of INCOLOY alloy 903 but with improved notch-rupture properties at elevated temperatures. Used for components of gas turbines including seals, shafts and casings.
STANDARD PRODUCT FORMS
Round bar and forging stock.
