Unalloyed boilersteel

Unalloyed pressure vessel steel is mainly used for applications with slightly elevated temperatures. Depending on the steel quality chosen, they can be used at temperatures from -50 ° C up to about 450 ° C, without losing their mechanical properties. These steels have excellent formability in both hot and cold conditions as well as excellent weldability.
