■ Overview
Normalised steel angle bars and L profiles S355N in steel standard en 10025-3 is mainly used to build steel structure,steel frames and other steel machines.When rolling steel angle bars s355nl,normalized heat treatment and low temperature impacting test shall be done in steel mill.And when issued the original mill test certificate for s355n angle steel,the Normalized word and the impacting test energy values have to be indicated on MTC.Else the product analysis of chemical composition values and mechanical property values also shall appear on MTC.
