ASTM AISI Nitronic 50 Xm-19 Alloy Steel Round Bar

ASTM AISI Nitronic 50 Xm-19 Alloy Steel Round Bar

1 . Description:

NITRONIC 50 Stainless Steel provides a combination of corrosion resistance and strength not found in any other commercial material available in its price range. This austenitic stainless has corrosion resistance greater than that provided by Types 316 and 316L, plus approximately twice the yield strength at room temperature. In addition, Armco NITRONIC 50 Stainless has very good mechanical properties at both elevated and sub-zero temperatures. And, unlike many austenitic stainless steels, NITRONIC 50 does not become magnetic when cold worked.

High Performance Alloys can make hot rolled, cold worked, & strain hardened High Performance Stainless Steel (HPSS) bars in house. Ask for our GFM Bulletin for more information about our bar processing capabilities. We have expanded to enhance product availability.

2 . Applications

Superior corrosion resistance

Almost double the yield strength

Exceptionally low magnetic permeability

Outstanding cryogenic properties

3 . Annealing Temperature
NITRONIC 50 Stainless Steel can be supplied annealed at 1950 F to 2050 F (1066 C to 1121 C). For most applications, the 1950 F (1066 C) condition should be selected, as it provides a higher level of mechanical properties along with excellent corrosion resistance. When as-welded material is to be used in strongly corrosive media, the 2050 F (1121 C) condition should be specified in order to minimize the possibility of intergranular attack.

4 . Corrosion Properties
Armco NITRONIC 50 Stainless Steel provides outstanding corrosion resistance - superior to Types 316, 316L, 317 and 317L in many media. For many applications the 1950 F (1066 C) annealed condition provides adequate corrosion resistance and a higher strength level. In very corrosive media or where material is to be used in the as-welded condition, the 2050 F (1121 C) annealed condition should be specified. High-Strength (HS) NITRONIC 50 bars are useful for applications such as shafting and bolting, but do not quite exhibit the corrosion resistance of the annealed conditions in all environments.
