What Are Cold Rolled finishes?StandardsPost Production Processing to Improve Corrosion ResistanceDifferences Between AlloysCold rolled finishes apply to flat products such as sheet or coil,with thickness less than about 5mm and usually less than 3mm.They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled.Cold rolling reduces the thickness by at least 50%.This smooths the surface,refines the grain structure and causes differences in the mechanical properties along and across the rolling direction.In the case of austenitic and duplex alloys,the proSee more on assda.asn.auFlanges - Flange Face FinishThe ASME B16.5 code requires that the flange face (raised face and flat face) has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal.A serrated finish,either concentric or spiral,is required with 30 to 55 grooves per inch and a resultant roughness between 125 and 500 micro inches.A Guide to Stainless Steel FinishesJun 17,2020 finishes for stainless steel ra surface finish holloway#0183;No.4 finishes show an Ra of 25 micro-inches or less with a highly reflective finish.Similar to No.3 finishes,No.4 finishes are used for general purposes.The uses for No.4 finishes are similar as well,as No.4 finishes are widely used for kitchen and restaurant equipment,food processing,dairy equipment,hospital surfaces,highway tank trailers,control panels,and water fountains.
