NB/T 47002 "Explosion welded clad plate for pressure vessels" consists of 4 parts: --Part 1: Stainless Steel - Steel Clad plate; --Part 2: Nickel-steel clad plate; --Part 3: Ti-steel clad plate; --Part 4: Copper-steel clad plate. NB/T 47002.1 replaces JB 4733-1996 "Explosive Stainless Clad Steel Plate for Pressure Vessels", and NB/T 47002.2 replaces JB/T 4748-2002 "Explosive nickel and nickel-base alloy clad steel plate for pressure vessels". The editions of NB/T 47002.3 and NB/T 47002.4 are the first formulation hereof. This standard is formulated according to the domestic production data and by reference to Japanese industrial standard JIS G3601-2002 "Stainless-clad steels", JIS G 3602- 1992 "Nickel and nickel alloy clad steels", JIS G 3603-1992 "Titanium clad steels" and JIS G 3604-1992 "Copper and copper alloy clad steels". There are major differences from JIS G 3601 ~ 3604 in the following aspects: --Add Class B1 clad plate with higher technical requirements and the percentage of unbounded area 0%; --Raise the combination shear strength index of the compound contact interface of rustless steel - steel clad plate and Nickel-steel clad plate; --The tensile test for clad plate is upgraded from the test item negotiated by the supply and demand parts to the required test item; --Add the test items of impact test; --The ultrasonic testing for Class B3 clad plate is upgraded from partial scanning to 100% scanning.
