1.4542 (X5CrNiCuNb16-4) is a well-established precipitation hardening martensitic stainless steel capable of achieving very high strength and hardness after a relatively simple heat treatment. It offers excellent corrosion resistance combined with a structured range of mechanical property levels depending on the precise heat treatment applied. It is readily machined and fabricated in the softer tempers and can then be heat-treated to exceptional strength and dimensional stability. It shows the following features and properties:
Offshore & marine: Offshore foils, helicopter deck platforms, pump shafts, couplings, fasteners, valve parts and spindles;Aerospace: Turbine blades, missile and rocket fittings, undercarriage components and fasteners;Other: Nuclear waste casks, medical instruments, paper mill equipment and chemical process plant, springs, screws, bolts, gears, bushes and wear rings
Very high corrosion resistance
It is readily machinable
