For the first time, the individual corrosion behaviour of both single phases in super duplex stainless steels was determined. The results show a good correlation with the empirical pitting resistance equivalent number (PREN) of the corresponding single phase.

Microstructure and Properties of Modern P/M Super

Precipitation of intermetallic secondary phases in duplex stainless steels is a well-known weakness of modern highly alloyed steel grades. Even relatively small amounts of these phases can severely deteriorate the mechanical and corrosion properties, the properties the duplex stainless steels are famous for. New challenges for the use of duplex stainless steels at sessing the low-temperature behavior of various heavy-wall duplex stainless steel forgings, hot isostatically-pressed (HIP) connectors and hot extruded pipes at temperatures down to 60 C. Several welding processes were also evaluated. The implications for the design of duplex On the effect of nitrogen on duplex stainless steels One of the key issues in the development of the modern duplex stainless steels was the introduction of nitrogen as an alloying element. This was made possible by e.g. the AOD process and has meant that the problems with earlier grades regarding weldability could be solved. The prime rea for the lower weldability, namely a coarse-grained heat affected zone with inferior properties was then unpolluted tongaprice of duplex stainless steel
