Surface treating.The surface treatment of steel also begins during hot-rolling,because reheating conditions,in-line scale removal,rolling temperature,and cooling rate all determine the type and thickness of scale formed on the product,and this affects atmospheric corrosion,paintability,and subsequent scale-removal operations.Sometimes the final pass in hot-rolling generates specificSteel - Shape and surface BritannicaSteel - Steel - Shape and surface In principle,steel is formed into either flat products or long products,both of which have either a hot-rolled,cold-formed,or coated surface.Flat products include plates,hot-rolled strip and sheets,and cold-rolled strip and sheets; all have a great variety of surface conditions.They are rolled from slabs,which are considered a semifinished product Steel - Encyclopedia Britannica BritannicaSteel,alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content,the material is defined as cast iron).By far the most widely used material for building the worlds infrastructure and industries,it is used to fabricate everything from sewing needles to oil tankers.In addition,the tools required to build and manufacture such articles are
