Type of Process Route and Surface Finish

	Symbol EN 2)	Symbol ASTM	Type of Condition	Surface Finish	Notes
Hot rolled	1U		Hot rolled, not heat treated, not descaled	Covered with rolling scale	Suitable only for products which are to be further worked.
	1C		Hot rolled, heat treated, not descaled	Covered with rolling scale	Suitable only for parts which will be descaled all over or machined after production.
	1E		Hot rolled, heat treated, mechanically descaled	Free of scale	The type of mechanical descaling is left to manufacturers discretion unless otherwise agreed.
	1D	No. 1	Hot rolled, heat treated, pickled	Free of scale	Usually standard for most steel types; also common finish for further processing.
Cold rolled	2H		Work hardened	Bright	Cold worked to obtain higher strength level
	2D	2D	Cold rolled, heat treated, pickled	Smooth	Finish for good ductility, but not as smooth as 2B
	2B	2B	Cold rolled, heat treated, pickled, skin passed	Smoother than 2D	Most common finish for most steel types to ensure good corrosion resistance, smoothness and flatness
	1G or 2G	No.3 to No.6	Ground 3)	See footnote 4.	Grade of grit or surface roughness can be specified.

Not all process routes and surface finishes are available for all steel grades.
First digit: 1 = hot rolled, 2 = cold rolled
One surface only, unless otherwise agreed at the time of ordering.
Within each finish description the surface characteristics may vary, and more specific requirements may need to be agreed between manufacturer and purchaser (grade of grit or surface roughness).
