ADDITIONAL INFO
Extremely corrosion resistant, XD15NW® exhibits similar characteristics to 440C, Cronidur® 30, and N360 (AMS 5898) in certain applications. It should be considered for corrosive, high-performance applications and may be a suitable candidate where other high-nitrogen grades are required. Interchangeability of grades depends on the desired material properties and should always be reviewed.
XD15NW®’s corrosion resistance has been tested against 440C using a salt spray test. The photo below compares both materials after 96 hours of exposure. For both grades, heat treatment cycles were as follows: 1050°C oil / -75°C / 180°C.
