■ Overview
Hot rolled shipbuilding steel plate NK Grade DH36 is a higher steel grade among shipbuilding steel.As for the heat treatment for NK Grade DH36,if the thickness above 12.5mm,the delivery condition must be Normalized or Normalized rolled or TMCP.As rolled is not allowed to delivery without the customer's special requirement.Heat treatment mark would be appear on our each steel plate as steel mark,such as Normalized would be marked as N,TMCP would be marked as TMCP which is short for Thermo-Mechanical Control Process.
