Overview
Austenitic Stainless
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. See more information on NITRONIC 50 HS (High Strength) properties on the NITRONIC 50HS page.

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.
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.
Intergranular Attack
The resistance to intergranular attack is excellent even when
sensitized at 1250 F (675 C) for one hour to simulate the
heat-affected zone of heavy weldments. Material annealed at 1950 F
(1066 C) has very good resistance to intergranular attack for most
applications. However, when thick sections are used in the
as-welded condition in certain strongly corrosive media, the 2050 F
(1121 C) condition gives optimum corrosion resistance.
Stress-Corrosion Cracking Resistance
In common with most stainless steels, under certain conditions,
Armco NITRONIC 50 Stainless Steel may stress-corrosion crack in hot
chloride environments. When tested in boiling 420/0 MgCI2 solution,
a very accelerated test, NITRONIC 50 Stainless Steel is between
types 304 and 316 stainless steels in resistance to cracking. There
is little difference in susceptibility to cracking whether in the
annealed, high-strength (HS), or cold-drawn conditions.
Sulfide Stress Cracking
Both laboratory tests and field service experience have shown that
Armco NITRONIC 50 stainless has excellent resistance to sulfide
stress cracking in air conditions. NITRONIC 50 in both the annealed
and high-strength (hot rolled) conditions has been included in the
1996 revision of NACE Standard MR-01 -75' "Sulfide Stress Cracking
Resistant Metallic Material for Oil Field Equipment," at hardness
levels up to RC 35 maximum. The resistance to cracking in
laboratory tests in synthetic sour-well solution(5% NaCI + ½%
acetic acid. saturated with H2S)
