Description

P 2000 is a Ni-free austenitic CrMnMoN-steel with 17% Cr, 12% Mn and 3.5% Mo being electro-slag remelted under pressure leading to a Nitrogen content of 0.9%. By an optimal combination of Cr-, Mn-, Mo- und N-additions the steel shows an outstanding corrosion resistance and an exceptional combi-nation of strength and ductility, compared with the implant steel 1.4441 (316L). Additional electro slag remelting stabilises the austenite and improves the cleanliness.

Application areas

The Ni-free steel grade P 2000 shows excellent biocompatibility and will be used mainly in contact with the human body, for the production of spectacle frames, watch cases and jewellery and after biological evaluation for the production of prosthesis for orthopaedics, bone screws and plates for osteosynthesis and high-strength wire for orthodontia.

Additional applications result inevitably in cases where corrosion resistance, reliability and a high fa-tigue resistance are required. Examples are ultra high strength screws, nuts and bolts for the fastener industry.
