Monel K-500 Alloy K-500 alloy steel plate alloy steel bar alloy steel pipe alloy steel wire
Product Description
The alloy k-500 is a nickel-copper alloy that combines the excellent corrosion resistance of alloy 400 with greater strength and hardness.The alloy k-500 provides three times higher yield strength than the alloy 400.These enhanced properties are mainly obtained by adding aluminum and titanium elements to nickel as the main elements and by aging hardening.During the aging hardening process, a small amount of Ni3(titanium, aluminum) particles were precipitated into the matrix.The k-500's low permeability, high strength and good corrosion resistance have been widely used, mainly in oil well detection equipment and electronic parts.An important property is that the k-500 is nonmagnetic even at very low temperatures.Aging hardening will produce initial volume shrinkage.In the aging hardening process, the round rod with diameter of 2.5 x 10-4 in is shrunk.For optimal performance, the typical aging hardening process is described belowAt 982 ° C for 30 minutes and then water quenched annealing.At 593 ° C to 607 ° C to keep 16 hours later with the slow cooling furnace 9.4 ° C - 3.8 ° C per hour up to 482 ° C.After cooling to room temperature from 482 ° C, it may take some boiler cooling, air cooling or quenching, without considering the cooling rate.
Monel400 is a kind of corrosion resistant alloy with the largest amount, the widest application and excellent comprehensive performance.This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated alkali solution.It is also resistant to corrosion of neutral solution, water, seawater, atmosphere and organic compounds.An important feature of the alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.
MONEL k-500 alloy has the same corrosion resistance as 400, but has higher mechanical strength and hardness.
Good resistance to heat and corrosion and long-term stability of microstructure.
Mainly used in the manufacture of aircraft engine working temperature below 750 ℃ on the turbine blade and gas turbine blades;Used for making fasteners and springs on ships;Pumps on chemical equipment
