Section 11

No.1 Finish → Hot-rolled,annealed and descaled.                                          

No.2D Finish → 

Cold-rolled,dull finish                                               

No.2B Finish → Cold-rolled,bright finish                                                       

Bright Annealed Finish → 

A bright cold-rolled finish retained by final annealing in a controlled 

atmosphere furnace                                                  

No.3 Finish → Intermediate polished finish,one 

or both sides                     

No.4 Finish → General purpose polished finish,one or both sides                     

No.6 Finish → Dull satin finish,Tampico brushed,one or both sides                        

No.7 Finish → High luster finish                                                  

No.8 Finish → Cold-worked to obtain specified properties.

Section 12

No.1 Finish → Cold-rolled to specified thickness,annealed and descaled                                         

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                                                  

TR Finish → Cold-work to obtain specified properties                            

Polished Finish → Stainless steel strip is also available in polished finishes such as 

No.3 and No.4,which are explained in Note4.                   

Section 13

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

Section 14

No.1 Edge → A rolled edge,either round or square as specified

No.3 Edge → An edge produced by slitting.

No.5 Edge→ An approximately square edge produced by rolling or filing after slitting
