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
Full Hard – 2R 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
