UNS N05500
N05500
N05500 has approximately three times the yield strength and twice the tensile strength of Monel 400, and higher mechanical properties can be obtained by cold working or age hardening. N05500 alloy has the same corrosion resistance as Monel 400 alloy.
N05500 alloy is mainly used for pump shafts and impellers, conveyor scrapers, oil well drill rings, elastic parts, valve pads, etc. Others can also manufacture various heat exchange equipment, boiler feed water heaters, petroleum and chemical pipelines, containers, towers, tanks, valves, pumps, reactors, shafts, etc. Due to the low corrosion rate in flowing seawater and the high strength of this alloy, N05500 is suitable for the manufacture of seawater corrosion resistant centrifugal pump shafts. It is suitable for static and flowing seawater.
Executive standard: ASTM B 865, AMS 4676.
Monel K-500 Machine Plus
The annealed state is easy, and the aging state processing is also possible. Usually large-scale machining in the annealed state, leaving a small amount of machining allowance and machining to final size after aging heat treatment. Slight shrinkage after aging processing. N05500 can be welded by industrial welding methods, but it must be done in the annealed state, and the stress must be relieved before aging. The aging process should be as fast as possible.
Monel k-500 (UNS N05500) First, the standard number: ASTM B865-04 (rod)
characteristic:
Monel K500, also known as UNS N05500, has the same corrosion resistance as Monel 400, but with higher mechanical strength and hardness.
Has good thermal corrosion resistance and long-term tissue stability.
Application areas:
It is mainly used to manufacture turbine blades and gas turbine blades with a working temperature below 750°C on aero-engines; it is used to manufacture fasteners and springs on ships;
UNS N05500 (W.Nr. 2.4375) is a nickel-copper alloy that provides the excellent corrosion resistance of UNS N04400 (Mone®l 400) with the benefits of higher strength and hardness. Higher performance is achieved by adding aluminum and titanium to the nickel-copper matrix and heating it under controlled conditions to precipitate submicroscopic particles of Ni3(Ti, Al) throughout the matrix. The heat treatment used to affect precipitation is often referred to as age hardening or aging.
Typical applications for UNS N05500 (W.Nr. 2.4375) products are marine chains and cables, fasteners and springs; pump and valve components for chemical processing; scrapers and scrapers for pulp processing; oil well collars and tools ; pump shafts and impellers, non-magnetic housings, safety lifts and valves for oil and gas production; and sensors and other electronic components.
UNS N05500 (W.Nr. 2.4375) is an acceptable material for bolts recognized by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code.
UNS N05500 (W.Nr. 2.4375) alloys are available in pipe, sheet, strip, plate, round bar, flat bar, forging, hexagonal bar and wire.
The chemical composition of UNS N05500 (W.Nr. 2.4375) is as follows:
UNS N05500(W.Nr. 2.4375) Density: 8.44g/cm3
UNS N05500(W.Nr. 2.4375) Melting point: 1315-1350ºC
UNS N05500 is produced by adding aluminium and titanium to the UNS N04400 nickel-copper composition, with proper heat treatment resulting in sub-microscopic gamma precipitation throughout the matrix. The typical microstructure of the hot-rolled material in the hot-rolled state is shown in the figure below
8 Corrosion resistance
The corrosion resistance of UNS N05500 is basically comparable to that of UNS N04400 alloy, but under age hardening conditions, alloy N05500 has a greater tendency to stress corrosion cracking in some environments.
UNS N05500 has been found to be resistant to sour gas environments. U-bend specimens of age-hardened panels did not crack after 6 days of continuous immersion in saturated (3500 ppm) hydrogen sulfide solutions at acidic and basic pHs (1.0 - 11.0). The hardness of the test piece is between 28 and 40 Rc.
The combination of extremely low corrosion rates and high strength in high-velocity seawater makes UNS N05500 alloy particularly suitable for marine centrifugal pump shafts. In stagnant or slow-moving seawater, fouling may occur after pitting, but this pitting slows down after a fairly rapid initial attack.
solution annealing
UNS N05500 is hardened by the formation of submicroscopic particles of the second phase Ni3(Ti,Al). The formation of these particles is a solid state reaction that occurs during age hardening (or precipitation hardening) heat treatments. Prior to the aging treatment, the alloy components should be solution annealed to dissolve any phases in the alloy that may have formed during previous processing. Solution annealing typically involves heating hot work products to 1800°F and cold work products to 1900°F.
Work Annealed
During machining and subsequent forming of UNS N05500 alloy products during production, intermediate process annealing may be required to soften the product. This annealing recrystallizes the structure and is typically performed between 1400-1600°F.
age hardening
For maximum performance, the following age hardening procedures are recommended
1. Soft material (140-180HB, 75-90 Rb).
Hold at 1100-1125°F for 16 hours, then furnace cool to 900°F at 15--25°F/hour. Furnace or air cooling or quenching from 900°F to room temperature regardless of cooling rate.
2. Medium cold work material (175-250HB, 8-25Rc)
Hold at 1100-1125°F for 8 hours or more, then cool to 900°F at no more than 15-25°F/hour. Higher hardness is obtained by holding at temperature for 16 hours, especially when the material is only lightly cold worked. In general, materials with an initial hardness of 175-200HB should remain intact for 16 hours. Materials approaching 250HB (25Rc) should reach full hardness within 8 hours.
3. Full cold working material (260-325HB, 25-35Rc)
Hold at 980-1000°F for 6 hours or more, then cool to 900°F at no more than 15-25°F/hour. In some cases, slightly higher hardness (especially for materials near the low end of the hardness range) can be achieved by holding at temperature for 8-10 hours.
