Monel 400 K500 High Temperature Anti Corrosion Alloy Strip Rod Wire
Nickel Alloy Monel K-500, the age-hardenable alloy, which contains aluminum and titanium, combines the excellent corrosion resistance features of Monel 400 with the added benefits of increased strength, hardens, and maintaining its strength up to 600°C.
The corrosion resistance of Monel K-500 is essentially the same as that of Monel 400 except that, in the age-hardened condition, Monel K-500 is more susceptible to stress-corrosion cracking in some environments.
Some of the typical applications of nickel alloy K-500 are for pump shafts, impellers, medical blades and scrapers, oil well drill collars, and other completion tools, electronic components, springs and valve trains. This alloy is primarily used in marine and oil and gas industrial applications. In contrast Monel 400 is more versatile, finding many uses in roofs, gutters, and architectural parts on a number of institutional buildings, tubes of boiler feed water heaters, seawater applications (sheathing, others), HF alkylation process, production and handling of HF acid, and in refining of uranium, distillation, condensation units, and overhead condenser pipes in refineries and petrochemical industries, and many others.
