Nitronic 50 Round bars

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 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.

Best Stainless supplies high quality Nitronic 50 high strength stainless steel.  Nitronic 50 stainless steel is an austenitic grade providing corrosion resistance greater than other typical austenitic grades such as SS 316/316L and 317/317L. It is also capable of nearly double the yield strength of similar austenitic grades. Nitronic 50 (XM-19) stainless steel offers yield strength three times that of 316. Our inventory of stock shapes includes Nitronic 50 rounds bar and pump shaft quality bar.

High Performance Alloys can make hot rolled, cold worked, & strain hardened High Performance Stainless Steel (HPSS) bars in house. The high strength, corrosion resistance, and low magnetic permeability of this alloy allow it to be used as a material for medical implants.

  • High strength austenitic alloy
  • Good corrosion resistance
  • Low magnetic permeability

Welding of stainless steel grade Nitronic 50 can be performed using traditional joining processes. Recommended filler metal should be Nitronic® 50W (AWS E/ER209).

Caution should be taken while using autogenously, high power density joining processes such as EB or laser welding, due to low FN potential and severe out gassing possibility.
