Online Information Centre for Stainless Steel in Construction
Fabrication & Installation > General
This resource is an information and guidance note aimed to help plant designers and operators realise the opportunities where selecting stainless steel for applications in the water industry will yield economic benefits. The material properties of stainless steel are described and the finishes noted. Guidance is then given on material selection for corrosion resistance, design of structural members, tanks and pipework systems, fabrication and installation. Finally the economic benefits in the form of savings are summarised for initial installation, operating and life cycle costs.
This resource provides information on the design, specification, manufacture and maintenance of stainless steel architectural components. The ‘Design and Technology’ section includes structural and performance information on stainless steel and reviews production and finishing techniques. The ‘Case Studies’ section provides numerous examples of the contemporary use of stainless steel in architecture. In each case the design criteria, finish, joining techniques, structural drawings and images for the stainless steel element are described and presented. The Appendices summarise the standards relating to stainless steel, the mechanical and physical properties the product range and the finish designation.
This resource is a guide aimed to provide engineers, architects and fabricators with the properties and capabilities of iron, carbon steel and stainless steel castings. Castings provide high strength, ductility and toughness, efficient production methods, excellent surface finish, and have good welding and machining characteristics. These properties allow savings on materials and minimise manufacturing costs. This guide explains the basic processes and techniques of castings and provides information for the designer on welding, surface finishes, tolerances and inspection and testing methods. It emphasises the importance of correct specification of the casting techniques and the appropriate level of quality. The procurement process is explained and illustrated with flowcharts. Appendices give examples of recent projects using structural castings, including 4 detailed case histories featuring main truss connections, glazing connections, beam to column connections and compression members in a bridge. Lists of sources of further information and the addresses of some UK foundries are also given.
This resource is a critical review of the literature relating to health effects associated with stainless steels, from manufacture through to processing and end use. It is aimed to provide an evaluation of the health hazards against the EU classification criteria. The material itself, the manufacture and the processing (cutting, polishing, forming) of stainless steel is then assessed for hazards for exposure, toxicokinetics and toxicity and finally any further research resources are noted.
Manufacturers and users do not always fully understand the importance of restoring a clean stainless steel surface after fabrication. Euro Inox has published a concise paper, which explains why, when and how post-fabrication surface treatment should be applied.
Table of contents:
WHY SURFACE FINISHING IS IMPORTANT
- Grinding and polishing
- Water jetting
- Acid pickling by immersion
- Swabbing – pickling with paste
- Cleaning with passivation
- Pickling different stainless steel grades
- Finishing treatments for welds, oxide scale and heat tint
- Free iron contamination
NEUTRALISATION AND WASTE TREATMENT
- Acid descaling (pickling) of stainless steel
- Acid cleaning conditions for stainless steel
- The principle of galvanic corrosion
- Relevant factors and examples
- Practical experience in different applications
- Preventing galvanic corrosion
Experience shows that the compatibility of different metals in mixed-material assemblies is an often-neglected aspect of design, fabrication and installation. This is particularly relevant when “noble” materials like stainless steel are used in direct contact with other, more common metallic materials. While this is does not normally affect stainless steel, the less corrosion-resistant partner metal may suffer accelerated corrosion. The brochure explains the underlying principle of galvanic corrosion and gives guidance towards – usually simple – precautionary measures that prevent unwanted reactions. It provides practical examples from building and construction, water and sewage treatment and plumbing. It enables the reader to find out which material combinations are safe and which require special attention. The brochure gives advice on practical methods of preventing galvanic corrosion.
This resource is a detailed review of ferritic stainless steels with the aim of promoting their use. As ferritic stainless steels do not contain nickel, their price is relatively stable. The chemical composition, mechanical and physical properties, welding techniques, fabrication practices and available product forms are all listed. Examples are given demonstrating the use of ferritics in a wide range of sectors.
