SURFACE FINISHES AND SURFACE CONDITION
Designation to ASTM A 480 / BS 1449 Part 2	Designation to DIN 17 440	Description	Surface Condition	Uses
No. 1 Finish	II a or C 1               II a or C 2	Hot rolled annealed, shot blasted and pickled	Mechanically & chemically clean	Used for general fabrication application including tubing / piping where finish is not so important
CR	III a or f	Work hardened	Smooth and bright smother than by process c 2 or II a	Used where high yield and tensile strength are required and corrosion resistance is not so important
CR - Unpickled	III s or g	Cold rolled annealed and not pickled	Thin layer of mill scale	Used for high stainless steel
2D	III b or h	Cold rolled annealed and pickled	Dull, but smoother than by process II a	Uniformally dull finish, normally used in forming deep drawn articles which may be polished after fabrication
2B	IIIc or n	Cold rolled annealed and pickled and skin passed	Dull, but smoother than by process II b	Commonly produced the same way as 2D except that colled rolled pass is given on polished rolls on 2D finish. More readily polished than No. 1 & 2D
