k500For over 20 years Best Stainless has been the premier suppliers of Monel K500. Monel K-500 is a precipitation hardenable nickel copper alloy. K500 brings characteristics similar to Alloy 400 in respect to corrosion resistance, however, offers higher yield and tensile strength. Having characteristics of high corrosion resistance, K-500 is an ideal alloy for use in marine environments when the need for constant contact with salt water comes into play.
