Accreditation Administration System:
With the minimum yield strength 355 Mpa,P355N and P355NH steel plate under standard EN10028_3
which mainly used to manufacture boilers,pressure vessels,drums,pressure or steam piping,heat
exchangers and industrial thermal vessels due to their high resistance to pressure at high temperature.
As the name of P355N and P355NH,P is short for pressure vessel steel plate,355 is its minimum yield
strength,N is for heat treatment Normalized or Normalized rolling,H is for high temperature usage.
Our mill rolling range for these boiler steel plates,the thickness shall be from 8 to 350mm,the width shall
be 1500_3000mm,the length shall be 5000_14000mm.If customers need the width belows 1500mm or
the length belows 5000mm,we can offer cutting services in our processing plant in Wuyang and Shanghai
city.However,our minimum cutting width shall be till 700mm,the length shall to above 2000mm.
