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 |
