No.2D Finish → Same as No.1 finish,followed by a final light cold-roll pass,

generally

on highly polished rolls

Bright Annealed Finish → A bright cold rolled finish retained by final

annealing in

a controlled atmosphere furnace

Hot-rolled or Cold-rolled,and Annealed or Heat treated → Scale not removed,

an

intermediate

finish,Use of plates in this condition is generally confined to heat-resisting

applications.

Scale impairs corrosion resistance.

Hot-rolled or Cold-rolled,and Annealed or Heat treated,and Blast cleaned or

Pickled

→ Condition

and finish commonly preferred for corrosion-resisting and most heat-resisting applications,

essentially a No.1 Finish.

Hot-rolled or Cold-rolled,and Annealed or Heat treated,and surface cleaned

and polishe

→ Polish finish is generally

No.4 Finish.

Hot-rolled or Cold-rolled,and Annealed or Heat treated,and Descaled; and

Cold-rolled,

and Annealed Or Heat treated,and Descaled,and Optionally temper passed

→ Smooth finish with

greater freedom from surface imperfections than in 13.1.4
