1.Description:
Nitronic 60 stainless steel provides a significantly lower cost way
to fight galling and wear compared with cobalt-bearing and high
nickel alloys.
Its uniform corrosion resistance is better than type 304 in most
media.In nitronic 60,chloride pitting is superior to type 316.
Yield strength at room temperature is nearly twice that of 304 and
316
Nitronic 60 provides excellent high temperature oxidation
resistance and low-temperature impact resistance.
2.Chemical composition
| Grade | C | Si | Mn | S | P | Cr | Ni | Fe | N |
| Nitronic 60 | ≤0.1 | 3.5-4.5 | 7-9 | ≤0.03 | ≤0.06 | 16-18 | 8-9 | base | 0.08-0.18 |
2.Applications:
Superior corrosion resistance
Almost double the 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
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.
