Abstract The relation between grain size and strength of the duplex stainlesssteels and the influence of grain size on the properties of hydrogen induced crack-ing in these steels have been investigated. The Hall-Petch relation between grainsize and strength of the duplex stainless steels is also followed. The susceptibilityto hydrogen induced cracking of the present steels increases with increasing grainsize.
