Description
Introduction:
X5CrNiCuNb16-4 is a corrosion resistant grade which is soft and ductile in the solution annealed condition. Medium to high strength, good toughness and strength is obtained by the appropriate ageing treatment. As a martensitic precipitation hardening stainless it is characterised by high tensile strength and high yield strength obtained by solution annealing, followed by a single or double low temperature age hardening treatment. X5CrNiCuNb16-4 has corrosive properties comparable to 304 austenitic stainless steel in many environments.
Applications:
Commonly used in industries such as offshore, marine, food, paper mills, oil field and aerospace. X5CrNiCuNb16-4 is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings.
