Monel K500 has excellent corrosion resistance in an extensive range of natural and chemical environments, excellent resistance to chloride-ion stress-corrosion cracking and very high strength and hardness. After age-hardening, Monel K500 has approximately 2 to 3 times higher mechanical properties than the nickel-copper alloy (Monel 400), high tensile properties up to about 650 degree C, good corrosion fatigue resistance and ow permeability with non-magnetic down to -135 degree C.Â
Monel K500 corrosion resistanceÂ
In general, the corrosion resistance of Monel K500 is similar to that of Monel 400. Excellent resistance is shown to a wide range of media from pure water to mineral acids, salts and alkalis.Â
Monel K500 is virtually immune to chloride-ion stress-corrosion cracking. In the aged condition, the alloy may be susceptible to stress-corrosion cracking in moist, aerated hydrofluoric acid vapour at stresses near the yield strength.Â
In high-velocity seawater and in marine atmospheres, good corrosion resistance is shown but, in slow-moving or stagnant seawater, pitting may occur. Nicorros Al also shows good resistance in sour-gas environments.Â
Monel K500 application fieldÂ
Monel K500 finds wide application in the marine, chemical, petrochemical and shipbuilding industries.Â
Typical applications include:Â
1. Valve seals, pump sleeves and wear rings in marineÂ
Environments high strength and resistance to seawater;Â
2. Fasteners, e. G. Bolts, used in marine atmospheres and tidal waters resistance to chloride-containing environments;Â
3. Doctor blades and scrapers;Â
4. Towing cable armouring high strength, non-magnetic properties and resistance to seawater;Â
5. Oil well drilling equipment such as non-magnetic drill collars, valves and instrumentation sleeves resistance to chloride-containing media and sour-gas environments;Â
6. Springs resistance to a variety of corrosive media;Â
7. Aviation instrument components non-magnetic properties.Â

The screw driver is a common tool used to turn the screw to make it in place. It usually has a thin wedge head, which can be inserted into the slot or notch of the screw head.
There are mainly one character (minus sign) and cross (plus sign). There are also common hexagon screw drivers, including two kinds of hexagon and hexagon. Each screw driver has different specifications and can be customized.
According to different head types, screwdrivers can be divided into one character, cross, meter character, star (computer), square head, hexagon head, Y-shaped head and so on. One character and cross are the most commonly used in our life, such as installation and maintenance. It can be said that as long as there are screws, screwdrivers will be used.
Hexagonal head is not used much, commonly used in the hexagonal wrench, such as some machines a lot of screws are with hexagonal hole, convenient for multi angle force. We don't see many big ones. Small ones are often used to repair mobile phones, hard disks, notebooks and so on. We call small screwdrivers clock batch. We often use star T6, T8, cross pH0, ph00 and so on.
