OEM Nickle Alloy Forging Bar Monel K500 Reaction Vessel Engine Components
Nickle Alloy Forging Bar:Using forging machinery to apply pressure to metal blanks to cause plastic deformation, thereby obtaining forgings with certain mechanical properties, shape, and size.
Rolling Bar: The process of reducing the cross-section and increasing the length of metal stock by passing it through the gap between a pair of rotating rolls (of various shapes) is known as rolling.
The Differences between Forging Bar and Rolling Bar:
- Forged parts typically have a denser structure than rolled round bar, as evidenced by the detection of porosity in the material through hot acid etching methods.
- Generally speaking, the quality of round bar produced by forging (referring to free forging here) is better than that produced by rolling. This is because forging requires repeated forging to achieve the same deformation as rolling for elongation (forging is free deformation, while rolling is constrained deformation).
- when the length of the round bar is relatively long, it is difficult to produce in one heat with forging (still referring to free forging here). Multiple heating and forging processes are required. In such cases, it is not easy to compare the overall quality differences between forged and rolled round bar.
- If advanced special forging methods (such as foreign advanced constrained forging and three-dimensional forging) are used, the quality of the forged round bar will always be higher than that of the rolled round bar.
Monel K500, is a age-hardenablenickel-copper alloy that combines the corrosion resistanceproperties of Monel 400 with high strength corrosion fatigue and erosion resistance properties. It is precipitation hardenable through theadditions of aluminum and titanium. The chemica composition of It retains the excellent corrosionresistant characteristics of alloy 400.When compared with Monel 400, it has enhanced strength and hardnessafter precipitation hardening. It has approximately three times the yield strength and doublethe tensile strength of alloy 400.It can befurther strengthened oy cold working before the orecipitation hardening. It should be annealed when welded and theweldment then stress relieved before aging.
Important properties:
- Similar corrosion resistance to Monel 400 but with higher strength and hardness
- Low permeability and non-magnetic at temperatures as low as -101°C (-150°F)
- Able to be age-hardened
- Suitable for seawater applications
Applications:
Typical applications for Monel K500 that take advantage ofhigh strength and corrosion resistance are pump shafts,impellers, propeller shafts, valve components for ships andoffshore drilling towers, bolting, oil well drill collars, andinstrumentation components for oil and gas production.ltis particularly well suited for centrifugal pumps in themarine industry because of its high strength and low corrosion rates in high-velocity sea water.

Machining:
Nickel based alloys can be difficult tomachinine.However, it should be emphasized that thesealloys can be machined using conventional productionmethods at satisfactory rates. These alloys harden rapidlygenerate high heat during cutting, weld to the cuttingtool surface and offer high resistance to metal removabecause of their high shear strengths. The following arekey points which should be considered during machining operations: capacity/tools/positive cut/lubrication.
