Brenton. TVP (Materials) 12 May 11 21:14. Kolsterising is about your only option, since Nitronic 50 does not respond to other thermal hardening processes, except nitriding. Roller burnishing will locally cold work (strain harden) the surface, so that may be an option too. BrentonB (Materials)

The microstructure of Nitronic ® 30, 40 and 50 series of 25 and 35 % cold worked, thermally aged at 750 C for 8 h, and annealed coupons was characterized by metallography, X-ray diffraction (XRD) and scanning electron microscopy. The coupons etching of each series needed specific attention and it resulted in an improved procedure.
Nitronic. Nitronic 50 (XM-19) UNS S20910 (22Cr-13Ni-2MO) is a very common stem material for the 316SS body of both ball and butterfly valves. From: A Practical Guide to Piping and Valves for the Oil and Gas Industry, 2021. View all Topics.
The shear modulus (G) is an important mechanical property for Nitronic 50 or XM-19 in hot rolled condition, as it measures the material's resistance to shear deformation. This is particularly important in applications where the material is subjected to high stress or impact loading.

The 'double-aged' H1150D condition is perhaps the most widely specified, giving a minimum yield strength of 105ksi / 725N/mm2. Therefore, it's the same strength of Nitronic 50HS, although the corrosion resistance is substantially less with a PREN >16 only. In terms of Nitronic 50 price, it is more expensive than duplex and super duplex ...
I need to approve a WPS for UNS S20910 Hot Rolled Material (also named Nitronic 50/XM-19). I found maximum hardness values in the base material zone up to 363 HV. NACE said "However, S20910 is acceptable in the annealed or hot-rolled (hot/cold-worked) condition at a maximum hardness of 35 HRC". NACE also said "Individual HRC …
