Jaka Burja (Institute of Metals and Technology)02/10/2019, 09:00Martensitic stainless steelsOral PresentationThe 17-4 PH is a precipitation hardening stainless steel with good mechanical and corrosion properties. Mechanical properties strongly depend on the heat treatment of the steel, namely, the isothermal ageing process. The formation of Cu-rich precipitates dictate the steel hardness, as they start to form the hardness rises, they coarsening however causes a substantial drop in hardness. However...Go to contribution page

Dr Herrera Clara (Deutsche Edelstahlwerke Specialty Steel GmbH & Co. KG)02/10/2019, 09:20Martensitic stainless steelsOral PresentationConventional martensitic stainless steels for use in bearings, stainless tools or cutlery require high carbon and chromium contents in order to achieve the desired properties. However, they are prone to precipitate coarse carbides, which is a drawback in strength and corrosion properties. High nitrogen martensitic stainless steels with a fine dispersion of carbides or nitrides, that show high...Go to contribution page

Chiara Tibollo (Technical University of Denmark)02/10/2019, 09:40Martensitic stainless steelsOral PresentationIn the present work high and low temperature (surface) hardening of X30Cr13 (AISI 420) martensitic stainless steel is addressed. High temperature solution nitriding (HTSN) was performed on thin specimens for obtaining a uniform distribution of nitrogen over the specimen thickness, reflecting the equilibrium nitrogen solubility. Three different nitrogen pressures were analysed, leading to three...Go to contribution page
