Stainless steel design guide welcomed


Design Guide 27: Structural Stainless Steel

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


Notes for editors

The guide will be launched at an event in New York on 18 September sponsored by AISC, the Steel Institute of New York and the Ornamental Metal Institute of New York.  More details can be found online at

IMOA is a non-profit trade association representing the interests of most of the world’s molybdenum producers and converters, as well as traders and end users.

Molybdenum is added to steels and cast irons 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.
