产品名称
INCOLOY 903
产品描述
A nickel-iron-cobalt alloy with additions of niobium, titanium and aluminum for precipitation hardening. The alloy combines high strength with a low and constant coefficient of thermal expansion at temperatures to about 800°F (430°C). It also has a constant modulus of elasticity and is highly resistant to thermal fatigue and thermal shock. Used in gas turbines for rings and casings.
STANDARD PRODUCT FORMS
Sheet, plate, rod, bar and forging stock.
