Accreditation Administration System:
Under the specification EN10025_3,normalized steel plate S420N and S420NL are used for welded
parts that have to bear high levels of strain.Especially used to bulid high briges,pylons and
other architectural structures.
These two steel grades S420N and S420NL are both need to be done Normalized heat treatment when
rolling.After delivery from our mill,we can accept the third party inspection by TUV,DNV,LR and
so on owning to these steel grades are normally adopted in European countries.At the same time,
our mill would issue the formal Mill test certificates for all items after doing all tests in
mill's lab.
Now we list the mainly chemical composition for steel plate S420N as belows:
Steel Grade Chemical Composition Max Heat Analysis C Si Mn P S Nb V S420N 0.20 0.60 1.00-1.70 0.030 0.025 0.05 0.20 Al min Ti Cr Ni Mo Cu N S420N 0.02 0.05 0.30 0.80 0.10 0.55 0.025
