Application scope
ASTM A480/A480M specifies the general delivery technical requirements for hot-rolled and cold-rolled thick plates, thin plates, and strips of stainless steel and heat-resistant steel. It serves as the foundational specification for use in conjunction with various product standards. The content covers common clauses regarding dimensional tolerances, appearance, surface finish, inspection, and testing. Grades span austenitic, ferritic, martensitic, and duplex structures, providing a unified basis for ordering, quality control, and acceptance of corrosion-resistant and heat-resistant steel plates.
Typical applications
As a universal delivery standard, it widely supports the procurement and acceptance of various stainless steel plates, serving many fields such as chemical industry, food processing, building decoration, and heat-resistant components. It is suitable for determining the surface condition, flatness, and dimensional tolerances of steel plates, helping manufacturers and users to reach a consistent quality agreement on thin plates, medium and heavy plates, and steel strips. It is often used in conjunction with specific material standards for equipment manufacturing and structural processing.
