The 2 mm stainless steel clad plate was twice-compounded rolled by φ500 mm and φ350 mm mills with 304 (20 mm) / 440 (3.5 mm) / 304(20 mm) stainless steels stock. The results by mechanical properties test and stnic- ture observation showed that the tensile fracture samples of clad plate hadn't stratification phenomenon
the grains at interplate mutually transferred interface to realize metallurgical bond
and the hardness of clad plate was higher to meet the requirement of knife products using.
