Clad type electromagnetic shielding material and method for manufacturing the same
A method for manufacturing a clad type electromagnetic shielding material includes step as follows: a first electrically conductive metallic layer, a magnetically conductive metallic layer, a second electrically conductive metallic layer and a shock-absorbing insulation layer, which are stacked in order, are one-time continuously rolled by a clad type rolling process, so as to finish a clad plate applied to an electromagnetic shielding field, wherein the surface of the shock-absorbing insulation layer provided with a binder faces the second electrically conductive metallic layer.
Ferritic stainless steel plate which has excellent ridging resistance and method of production of same
A ferritic stainless steel sheet having ridging resistance contains, by mass, 0.025 to 0.30% C, 0.01 to 1.00% Si, 0.01 to 2.00% Mn, 0.050% or less P, 0.020% or less S, 11.0 to 22.0% Cr, and 0.022 to 0.10% N. In addition, Ap, which is defined as 420C+470N+23Ni+9Cu+7Mn−11.5(Cr+Si)−12Mo−52Al−47Nb−49Ti+189 wherein each of Sn, C, N, Ni, Cu, Mn, Cr, Si, Mo, Al, Nb, and Ti denotes the content of the element, satisfies 10≦Ap≦70. Furthermore, a content of Sn satisfies 0.060≦Sn≦0.634−0.0082Ap. Residual ingredients are Fe and unavoidable impurities, and a metal structure of the steel sheet is a ferrite single phase.

PRESS FORMING METHOD AND PLATE MATERIAL EXPANSION DEVICE USED IN SAID METHOD
Provided are a press forming method capable of improving material yield while avoiding the risk of dimensional error increase at product forming sections in blank material when carrying out press forming, and a plate material expansion device used in this method. An end side of plate material for press forming is restricted by blank holding rollers, and pressure is applied to a middle location in the part that is restricted by a pressure roller. In this state, the plate material is transported in a rotating direction of the rollers being driven to continuously bend and extend the section receiving pressure. This bent and extended section is flattened with a flattening roller to obtain blank material wherein an end part is expanded.
