Monel K-500 Custom Springs
Monel K500 is a precipitation-hardenable nickel-copper alloy that has excellent corrosion resistance. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400. Monel K-500 has been found to be resistant to sour-gas environments.
