A method for producing a FeCr alloy comprises: rolling a slab having a chemical composition containing, by mass %, C: 0.020% or less, Si: 0.01% to 1.5%, Mn: 1.0% or less, P: 0.040% or less, S: 0.010% or less, Cr: 16.0% to 30.0%, Al: 2.0% to 6.5%, N: 0.020% or less, and Ni: 0.50% or less, with the balance being Fe and inevitable impurities to obtain a sheet material; subjecting the sheet material to siliconizing treatment by a thermal CVD method to obtain a FeCr alloy having a Si content of more than 1.5 mass % and 10.0 mass % or less and satisfying:
14.0%?Si+1.15?% Al+0.35?% Cr(1)
where % Si, % Al, and % Cr indicate Si, Al, and Cr contents, by mass %, respectively in the chemical composition of the FeCr alloy.

This application discloses methods of preparing a work roll for applying a dulled gloss finish on a metal substrate surface. The resulting finish has a fairly uniform glossiness with a slightly matted appearance and with minimal directionality. The work rolls have an Ra value of from 0.2 to 0.4 m and an Rz value of less than 3.0 m. Methods of forming a dulled gloss finish on a metal substrate are also described herein.

A rolled metal sheet includes an obverse surface and a reverse surface that is a surface located opposite to the obverse surface. At least either one of the obverse surface and the reverse surface is a processing object. A method for manufacturing a metal mask substrate includes reducing a thickness of the rolled metal sheet to 10 m or less by etching the processing object by 3 m or more by use of an acidic etching liquid, and roughening the processing object so that the processing object becomes a resist formation surface that has a surface roughness Rz of 0.2 m or more, thereby obtaining a metal mask sheet.

A refractory metal plate is provided. The plate has a center, a thickness, an edge, a top surface and a bottom surface, and has a crystallographic texture (as characterized by through thickness gradient, banding severity; and variation across the plate, for each of the texture components 100//ND and 111//ND, which is substantially uniform throughout the plate.

A method for manufacturing an aluminum alloy sheet may include melting aluminum alloy composition containing silicon (Si), iron (Fe), copper (Cu) and manganese (Mn) in weight % on the basis of remainder of aluminum (Al) to make cast alloy having a constant initial thickness; rolling the cast alloy to allow the initial thickness to be reduced, whereby the cast alloy is elongated to aluminum alloy sheet; and performing heat treatment on the aluminum alloy sheet.

This disclosure presents methods and/or processes for forming a garage door faade using variable pressure. The forming processes, different from common stamping processes, creates a shaded design in a garage door section such that a continuous pattern is realized in the length direction (i.e., the longest side of the garage door section). The forming processes also produces significantly deep and smooth impressions that deform the center of the design. The forming process may be preceded by a texturing process, for example, each garage door section may first be textured and then sent for forming the design.

A textured work roll can impart a desired texture on a metal substrate, such as an aluminum or aluminum alloy sheet. The textured work roll can be used for applying a gloss finish on the metal substrate. The textured work roll can be textured by grinding the work roll to form a ground work roll; electro-discharge texturing the work roll to form an electro-discharge textured work roll; and polishing the work roll to form a polished work roll. The polished work can have an Ra value between 0.30 m and 0.70 m. The polished work roll can be used to apply the gloss finish on the metal substrate.

An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions<1%. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 m to the surface of the sheet at low roll force.

The invention relates to sheet steel, more particularly a coated sheet steel, which is skin-pass rolled with a deterministic surface structure, and to a method for producing this steel.

The invention relates to a sheet metal plate (10) for creating flooring (30), in particular for industrial vehicles, having on its upper surface (11) a plurality or raised patterns, each raised pattern comprising one or more protruding portions (20), the raised patterns being arranged periodically, discreetly and in orderly fashion, the height h of the raised patterns being between 0.3 and 3 mm, characterized in that the plate has, on its lower surface (12), which is intended to be bonded to a support member, a rough surface the roughness Rmax of which is between 10 m and 250 m. The invention also relates to the method of producing said plate and the use of said sheet metal plate for creating flooring for industrial vehicles, preferably flooring for refrigerated vehicles.
