Stainless steel design guide welcomed
IMOA welcomes the publication, by the American Institute of Steel Construction (AISC), of Design Guide No. 27, Structural Stainless Steel, which fulfils the need for U.S. design recommendations for larger structural stainless steel sections and will make such projects much easier to specify.
Lighter gauge stainless steel sections were already covered by a US design specification, but no guidance existed for heavier sections, meaning that building enforcement officials had to individually approve each application.
An industry-wide effort, initiated by IMOA and involving stainless steel producers and industry associations saw the guide, authored by Nancy Baddoo, Associate Director at the Steel Construction Institute, become a reality.
"Up until now, there have been no specifications or guidelines for the design of structures fabricated from hot-rolled stainless steel plates or shapes," said Ted Galambos, Ph.D., P.E., emeritus professor of structural engineering at the University of Minnesota, who reviewed the guide. "This document, for the first time in the U.S., will show designers how to proportion stainless steel beams, columns, frames and connections that are fabricated from hot-rolled components."
The guide covers material behavior and selection, cross-section design, member design, connections, fabrication and includes design examples. It is written in the form of a specification, enabling designers to reference it as justification, eliminating a tremendous amount of work and creating new growth potential in applications like pedestrian bridges, buildings and other structures.
Steel Design Guide No.27, Structural Stainless Steel, is available to download from AISC’s website at www.aisc.org/dg
General information for media
IMOA is a non profit trade association, representing the majority of the molybdenum industry worldwide. It works to raise awareness about the unique properties of molybdenum, its beneficial effects on materials performance, its safety in use and its contribution to sustainable development.
Molybdenum is added to alloy steels to improve strength, toughness, hardenability and weldability for numerous applications in the automotive, shipbuilding, construction, mining, chemical, oil & gas and energy generation industries. In stainless steels and superalloys, it improves corrosion resistance and high-temperature performance and finds uses in many industrial applications. It is also used in a variety of products from catalysts and lubricants to pigments and paint.
IMOA has a strict antitrust compliance policy which delegates of all meetings are required to observe. All such meetings are observed by legal counsel.
