Accreditation Administration System:
Normalized steel plate S275N and S275NL Under the specification EN10025_4 which are mainly used for for
manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel
structures.
Signature of steel grade: S275N The cryogenic grades S...N are available for special applications at temperatures
below _20 centidegree. S275NL The cryogenic grades S...NL are available for special applications at temperatures
below -50 centidegree.
Welding:The fine_grain structual steel grades of this series can be perfectly welded both manually and using
automatic equipment by means of all known welding processes. However, the quality of the weld joint depends
on the welding process, the welding conditions and the selection of the correct filter metals.The welding wires
and electrodes approved in this strength category must be used as filter metals. Basic coated electrodes are
recommended for manual welding.Chemical composition for heat analysis as belows:
Steel Grade Chemical Composition Max Heat Analysis C Si Mn P S Nb V S275N 0.18 0.40 0.50-1.50 0.030 0.025 0.05 0.05 Al min Ti Cr Ni Mo Cu N S275N 0.02 0.05 0.30 0.30 0.10 0.55 0.015
In advantage of our widest steel resources in china,Yusheng iron and steel insist on offering the best quality and
high tech steel plates S275N and S275NL to vast customers.
