Ferritic stainless steel plate and method |
摘要 |
A ferritic stainless steel plate of excellent ridging resistance and formability, as well as a manufacturing method thereof are proposed. Specifically, the rolling is conducted at a rolling reduction of 30% or more in at least 1 pass and at a temperature difference between the center of the plate thickness and the surface of 200° C. or lower in a pass for the maximum rolling reduction to cause the area ratio of a {111}orientation colony to be present by 30% or more in the regions of ⅛ to ⅜ and ⅝ to ⅞ of the plate thickness. The {111}orientation colony is an assembly of adjacent crystals in which the angle of <111> orientation vector for each of the crystals relative to the direction vector vertical to the rolling surface is within 15°.
