   Abstract : The focus of this master’s thesis is on the heat treatment of Ni-base alloys, specifically the risk of intermetallic σ-phases during different stages of heat treatment. The alloy studied is Sanicro®28, a super-austenitic stainless steel produced by Alleima AB. READ MORE

3. 2. The Process Influence on Strength Properties of an Austenitic Stainless Steel (254 SMO)

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Anna Hellqvist; [2014]
   Keywords : stainless steel; hot rolling; levelling; strength; material properties; process parameters;

   Abstract : This work has been performed at Outokumpu Stainless AB, QPE, in Degerfors where focus is on production of hot rolled tailor-made quarto plate in special stainless steel grades such as highly alloyed austenitics and duplex steel grades. After a period with low values in strength and a lot of deviations in tensile tests for the highly alloyed austenitic stainless steel, 254 SMO, there was a need to investigate what influence some parameters during process has on strength values.
