What is the proper code for designing stainless steel? I'm using ASTM A276 standard hot-rolled/extruded shapes. ANSI/AISC 360-05 does not list A276 in Chapter A, but logically, why can't I use 360-05?
For cold-formed, you could use ASCE 8-02, Specification for the Design of Cold-Formed Stainless Steel Structural Members. I'm not sure what the equivalent for hot-rolled would be.
This is the Specialty Steel Industry of North America and provides a design code for SS.
Their website provides this:
The stress-strain behavior of stainless steel differs from carbon steel in several respects. The most important difference is that carbon steel typically exhibits linear elastic behavior up to a clear yield stress point while stainless steel has no well-defined yield stress point. After carbon steel reaches a clearly visible yield stress point, its strength plateaus. Stainless steel’s rounded stress-strain curve does not plateau and a 0.2% offset strain level is used to define yield strength.
Stainless steels have excellent ductility and strain hardening characteristics and can absorb considerable impact without fracturing. Their strength level also increases with work hardening.
Basic stainless steel mechanical and physical property design data is provided in Imperial and metric units. The most commonly used stainless steels are Types 304 and 316. Data has also been provided for 2205, which offers higher strength and corrosion resistance. Sources of detailed design guidelines and the relevant specifications are identified in the following section.

Stainless steel is in the European, Japanese, and Australian structural design codes. Unfortunately, it has not yet been included in North American structural design codes but stainless steel structural members are covered by numerous specifications.
ANSI/ASCE 8-90 is the Specification for the Design of Cold-Formed Stainless Steel Structural Members. This specification is widely used around the world for cold-formed structural stainless steel design.
