AISC Releases Updated Structural Stainless Steel Standards (ANSI/AISC 370-25 and ANSI/AISC 313-25)

FOR IMMEDIATE RELEASE

CHICAGO - The latest versions of two American Institute of Steel Construction standards, AISC Specification for Structural Stainless Steel Buildings (ANSI/AISC 370-25) and AISC Code of Standard Practice for Structural Stainless Steel Buildings (ANSI/AISC 313-25), are now available.

They can be downloaded for free at aisc.org/standards.

Developed by the AISC Committee on Structural Stainless Steel, the 2025 editions mark the second iteration of both standards since their 2021 debut. The updates ensure alignment with the 2022 standards for carbon steel (ANSI/AISC 360-22 and ANSI/AISC 303-22) while addressing the unique characteristics of stainless steel.

"The 2025 stainless standards represent a big step forward from their first editions," said Mark Holland, chair of the AISC Committee on Structural Stainless Steel for the 2021 and 2025 development cycles. "The committee worked hard to bring these updates forward on a short cycle as AISC continues to respond to the growing needs of the construction community to have the best information available in the area of structural stainless steel."

AISC 370-25 introduces improvements to the provisions for specifying alloys, new flexural design requirements for singly symmetric I-shaped members and single angles, and updates to the determination of shear strength of stainless steel bolts. AISC 313-25 provides a clear and consistent set of requirements for backoff and runoff tabs and standardizes terminology to match AISC 370.

American Institute of Steel Construction

The American Institute of Steel Construction (AISC), a not-for-profit technical institute supported by the steel industry, partners with the architecture, engineering, and construction (AEC) community to develop safe and efficient steel specifications and codes while driving innovation to make steel the most sustainable, economic, and resilient structural material. For more than a century, AISC has been a reliable resource for information and advice on the design and construction of domestically fabricated structural steel buildings and bridges.
