Basic Info
ASTM A666 is a standard specification for annealed or cold-worked austenitic stainless steel sheet, strip, plate, and flat bar. It covers the requirements for chemical composition, mechanical properties, dimensions, and surface finishes of stainless steel products. This standard is widely used in various industries, including automotive, aerospace, construction, and food processing, due to the excellent corrosion resistance, formability, and strength of austenitic stainless steels. ASTM A666 provides guidelines for both annealed and cold-worked conditions, offering flexibility in processing and fabrication. Compliance with this standard ensures consistency and quality in the production of stainless steel materials for diverse applications.
Characteristics
