: Hot-rolled, annealed, and descaled (dull, rough surface).
: Hot-rolled, annealed, and descaled (pickled). This results in a dull, matte surface, commonly used in industrial applications where appearance is secondary to corrosion resistance. Cold-Rolled Finishes astm a480 a480m pdf
Officially titled the Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip , it serves as an "umbrella" protocol. While material composition and mechanical strength are governed by specific grades (like ASTM A240 ), ASTM A480 sets the physical boundaries, structural consistency, and surface configurations necessary for industrial fabrication. : Hot-rolled, annealed, and descaled (dull, rough surface)
You buy material to A240 (chemistry/strength), but the mill ships it to A480 (dimensions/tolerances). and descaled (dull
