ADDITIONAL INFO
In certain applications or environments, XD16N can provide solutions to common material performance issues:
-
If 440C is corroding or underperforming, XD16N offers improved characteristics in nearly all respects. Manufactured by Aubert & Duval, XD16N is a true stainless with 58+ HRC hardness and provides superior fatigue and wear resistance for a price comparable to remelted 440C.
-
Other CREN grades such as XD15NW®, Cronidur® 30, and N360, may outperform 440C in corrosive applications, but at a higher price point. XD16N provides the optimal balance of performance and affordability while maintaining higher hot-hardness levels than other CREN grades.
-
High-temperature applications often call for BG-42®, a higher-cost and supply-constrained stainless steel. If BG-42® is out of budget or out of stock, XD16N is an ideal alternative with higher hot-hardness levels and stainless properties at a significantly cheaper price.
-
While similarly corrosion-resistant, XD16N is a significant upgrade in wear resistance to PH or 300 series grades.
XD16N’s corrosion resistance has been tested against 440C (X105CrMo17) using a salt spray test conducted according to NF X 41-002. The photos below show material surfaces after various salt spray exposure times.
Heat Treatment
Heat treatment instructions and recommendations for XD16N are provided by one of our mills, Aubert & Duval. Please contact Sullivan Steel for additional guidance or information.
Machinability
Sullivan Steel typically stocks XD16N in the annealed condition, optimal for machinability and heat treatment uniformity. Exceptions may apply.
Common Applications
Gears, valves, injection systems, blades, cutting tools.
