STAINLESS STEEL ALL THREAD ROD

Also see Stainless Steel: Types, Grades, and Standards
APPLICATIONS:

Stainless steel fully threaded rod for general use in harsh atmospheric conditions and some corrosive environments. Stainless steel has higher corrosion resistance than carbon steel. Stainless steel all thread rod is commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment. Some chemical environments may require special corrosion resistant materials and precautions.
