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.
