Domestic standards for nickel based alloy composite plates
Nickel based alloys are generally used as cladding materials for composite plates, and the base material can be carbon steel, low alloy steel, or stainless steel. All nickel based alloys mentioned above can be used to make nickel based alloy composite plates.
JB4748-2002 is a previously implemented standard for nickel based alloys. On May 1, 2010, NB/T47002.2-2009 Standard Explosive Welded Clad Plates for Pressure Vessels Part 2: Nickel Steel Clad Plates was implemented, officially replacing JB standard
The changes to the previous standards are as follows:
