DM Metalloys Pvt. Ltd. distinguished manufacturer, supplier and exporter of stainless steel 304/304L/316/316L in NO. 4 finish. No 4 finish is duller than the other mutual finishes, 2B and BA and is commonly used where lower reflectivity or gloss is mandatory and where welds and other fabrication marks are to be refinished to match the innovative surface. This is not possible with 2B and difficult with BA. Abrasive belts have very fine grains of refractory material such as silica, alumina and zirconia entrenched in an adhesive layer on a flexible cloth or paper backing. The belts in NO.4 finish are wider than the stainless steel, which is usually worked on as coil, or sometimes in individual sheets. The steel is run slowly under rolls, on which the abrasive belts run.
