Clad steel plates -
Mechanical and technological test
1 Scope
This standard specifies the tensile test, shear test, bend test, bond test, impact test, combine test and hardness test of clad steel plates.
This standard is applicable to the mechanical and technological tests of single side and both sides clad steel plates (hereinafter referred to as clad steel plates) manufactured by rolling, explosion, overlaying, diffusion, casting, explosion rolling, overlaying rolling, diffusion rolling and casting rolling with steel plates as the base metal and stainless steel or nonferrous metal and alloy as the cladding metal.
It may also be referenced by other metal clad plates.
