Strip steel is extremely versatile, mainly used in the automotive industry, machinery manufacturing industry, construction, steel structures, daily hardware and other fields, and is the raw material for cold-rolled strip, cold-formed steel, welded steel pipes and other steel. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving.
For example, Q195-Q345 steel and other grades of strip steel can be used for welded pipes; 10#-40# strip steel are to make precision pipes; 45#-60# strip steel are common materials of blades, stationery, tape measures; 40Mn, 45Mn, 50Mn and 45B steel grade can be made into chains, chain blades, stationery, knives and saws; 65Mn and 60Si2Mn are as materials of springs, saw blades, clutch leaf plates, clockwork; saw blade; scalpels, razor blades are made of T8A and T10A steel. In addition, there are bicycle frames, wheel rims, door and window hinges, handles, and containers (SPA-H), etc.
Strip steel is divided into ordinary strip steel and high quality strip steel; according to the processing method, there are two kinds of hot strip and cold strip. Typical processes for cold strip steel are: pickling - cold rolling - annealing - cold rolling - slitting - forming heat treatment.
Commonly used strip grades are 08F, 10F, 15F, 08AI, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 50Mn, 60Mn, 65Mn, 70Mn, 40B 50B, T8A, T10A, etc.
