KLEINOX 4034 (AISI 420) hardenable martensitic stainless steel with a low S content. In order to obtain a satisfactory corrosion resistance, the machined parts must previously be tempered, polished and passivated. In these conditions, this grade has a similar wear resistance as its equivalent grade KLEINOX 4035 with a higher S content. It is well adapted for the production of turned parts and medical, surgical and dental instruments as well as in the agro and food industries.
