Hot-finished or cold-finished bars, including rounds, squares, hexagons, and other structural shapes.
The "story" of A564 is the story of how metallurgists solved a century-old problem: Stainless steel (like 304 or 316) is corrosion-resistant but often too soft for heavy load-bearing applications. High-strength steels are hard but rust easily. ASTM A564 covers the alloys that bridge this gap. They are corrosion-resistant like stainless steel but strong enough to be used in landing gear and nuclear reactors. astm a564 pdf
is the standard specification for hot-rolled and cold-finished age-hardening (precipitation-hardening) stainless steel bars and shapes. These materials are unique because they offer the excellent corrosion resistance of austenitic stainless steel combined with the high strength of martensitic or low-alloy steels.
