Abstract: A Ni-plated steel sheet includes a base steel sheet and a Ni-based coating layer that is disposed on a surface of the base steel sheet. The distribution of carbon concentration in a depth direction obtained by performing GDS analysis on the Ni-plated steel sheet has a peak indicating the carbon concentration that is equal to or more than twice the carbon concentration of a thickness middle portion of the base steel sheet in the vicinity of an interface between the base steel sheet and the Ni-based coating layer.

Abstract: The application relates to a polymerization vessel and a method for manufacturing the same. An interior surface of the polymerization vessel has a specific structure, so that the polymerization vessel has better heat transfer efficiency. Closed cooling channels are constructed from the specific structure, and therefore cooling fluid flows in the closed cooling channels. Furthermore, there won't be any by-pass defects in the cooling channels of the polymerization vessel, thereby improving cooling efficiency of the cooling fluid.
