This resource tabulates information about the cleaning of stainless steel. The table firstly describes the cleaning requirement, ranging from light soiling to heavily neglected surfaces with grime deposits and paint stains. The cleaning method is then explained for each case, detailing the use of detergents, chemical liquids, pastes, abrasive brushes etc.
This resource describes the surface treatments known as pickling and passivation that can be applied to stainless steel. Pickling uses nitric and hydrofluoric acids to remove a thin layer of metal from the surface. Passivation uses nitric acid to improve the quality and thickness of the passive layer on the surface. Procedures for removing weld heat tint and rust contamination are explained.
This resource aims to demonstrate the significant forming potential of stainless steel. The effect of forming on the mechanical properties for each stainless steel family is presented. The most commonly used finishes are then described with reference to EN 10088 Part 2. The article then uses 9 case studies on mechanical parts (pumps, rims, heat exchange plates, etc.) to demonstrate the range of applications stainless steel can be used for - techniques such as hydro-forming, cold rolling, metal spinning, explosion forming and deep drawing are explained.
This resource outlines mechanical finishing methods that are appropriate for stainless steel fabrications, describing and illustrating current "best-practice" and emphasizing some of the differences between carbon steel and stainless steel practice. Frequently used finishing methods such as grinding, polishing, buffing and brushing are described. The use of hand tools such as abrasive belts and discs as well as powered equipment such as fixed and portable finishing tools are explained. A guide to best finishing practice is also given. Case studies demonstrating a stainless steel finish are presented, covering the fabrication and installation procedures. Also available on CDROM which includes 2 video presentations showing examples of the operations involved.
