NITRONIC 50 HS High Strength Nitronic Alloys UNS S20910

   NITRONIC 50 HS High Strength (UNS S20910)

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 type 316 and 316L,plus approximately twice the yield strength at room temperature.In additional,Armco Nitronic 50 stainless has very good mechanial properties at both elevated and sub-zero 

temperatures.And,unlike many austenitic stainless steels,nitronic 50 does not become magnetic shen 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. Bars are stocked and manufactured according to Cond. S or Cond H high strength properties, we also makea full line of materials in high strength bar, sheet and plates according to your specification.

2 . High Strength (HS) Bar Properties

NITRONIC 50 stainless bars also are available in a high-strength condition attained by special processing techniques. Because its high strength is produced by mill processing, hot forging or welding operations cannot be performed on this material without loss of strength. High-strength bars produced by rotary forging-special practice may have somewhat reduced resistance to corrosion and sulfide stress cracking not exhibited by strain hardened materials. This is primarily due to the hot worked material becoming sensitized during processing.

3 . Applications

• Superior corrosion resistance
• High yield strength
• Exceptionally low magnetic permeability
• Outstanding cryogenic properties

Outstanding corrosion resistance gives Armco's NITRONIC 50 Stainless Steel the leading edge for applications where Types 316. 316L, 317 and 317L are only marginal. It's an effective alloy for the petroleum, petrochemical, chemical, fertilizer, nuclear fuel recycling, pulp and paper, textile, food processing and marine industries.

• Components using the combination of excellent corrosion resistance and high strength currently include pumps, valves and fittings, fasteners, cables, chains, screens and wire cloth, marine hardware, boat and pump shafting, heat exchanger parts, springs and photographic equipment.
• Fastener - High strength, and higher strength fasteners can improve the durability of you equipment
• Marine hardware - Mastings, tie downs
• Marine and Pump shafts - better corrosion than types 304 and 316, with double the yield strength.
• Valves and fittings - better corrosion than types 304 and 316, with double the yield strength.
• Downhole rigging - better corrosion than types 304, 316 and 17-4, with double the yield strength in annealed condition.
• Reduced cross sections - better corrosion than types 304, 316 and 17-4.
