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 316L and 317L, plus approximately twice the yield strength at room temperature as annealed. In addition, Nitronic^® 50 offers very good mechanical properties at both elevated and sub-zero temperatures. In Hot rolled conditions the mechanical properties a strongly improved.  Unlike many austenitic stainless steels, Nitronic^® 50 does not become magnetic when cold worked. EXCELLENT FOR SEA WATER SERVICE.

NITRONIC^® 50 HOT ROLLED

NITRONIC^® 50 can be available as hot rolled with mechanical properties according to ASTM A479 HOT ROLLED up to 4" dia. Ask for our Bulletin for more information about our bar processing capabilities. We have expanded to enhance product availability. 

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.

NITRONIC^® 50 Stainless Steel provides outstanding corrosion resistance - superior to types 316, 316L, 317 and 317L in many media. Totally safe in sea water service. For many applications the 1950 F (1066 C) annealed condition provides adequate corrosion resistance and a higher strength level. 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.

NITRONIC^® 50 also in HOT ROLLED CONDITIONS can be full certified to ASTM 262 Practice E - intergranular corrosion test.

Both laboratory tests and field service experience have shown that 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)
