Carpenter’s EXPERIMENTAL 290 ALLOY is a Co-free, high strength high toughness alternative to 300M. The EXPERIMENTAL 290 ALLOY has a 290 ksi minimum UTS combined with a 70 ksi√in. minimum KIC. The EXPERIMENTAL 290 ALLOY also has a rotating bending fatigue test run-out stress of 145 ksi. This presentation will discuss the metallurgy of the EXPERIMENTAL 290 ALLOY and compare its properties to 300M and Carpenter AerMet 100 alloy. Stress Corrosion Cracking resistance in 3.5% NaCl will also be discussed.
