Refers to the width 12-300mm, thickness 3-60mm, cross section is rectangular in shape and with a blunt edge of steel.Flat steel can be finished steel, also can do the pipe blank and roll sheet of thin slab.
Main purposes: as a flat timber can be used to make hoop iron, tools and mechanical parts, building frame structure, escalator for real.Drawing polishing stainless steel and hot-rolled stainless steel of white sand acid.
Production standards for stainless steel flat bar

GB9787—88/GB9788—88:Hot rolling dimensions, shape, weight and tolerances.
JISG3192—94:Shape, size, weight and tolerance of hot rolled steel.
DIN17100—80:Quality standard for common structural steel.
ГОСТ535—88: Technical conditions of ordinary carbon steel.
Inspection for Chemical composition and physical property
Chemical inspection
Composition standard:The chemical composition of stainless steel rolling steel series for general
structure, the main test index for C, Mn, P, S four.
According to different grades, the content of each difference, roughly the
range of C<0.08%, Mn:2.0, P<0.035%, S<0.03%.
Inspection method: Detection of the chemical composition, test methods commonly used standard
GB223, JISG1211, BS1837, BS - 1215, 19 F C, manual is 22536.
Property inspection
property standard: The test items of the performance test are tensile test and bending test.
The indexes include the yield point, tensile strength, elongation and bending.
Inspection method: Tensile test method:Method for inspection of commonly used standard GB/T228-87
JISZ2201, JISZ2241, ASTMA370, BS18, C, f is 1497 and DIN50145.
Bend test method: Method for inspection of commonly used standard GB/T232-88, JISZ2204, JISZ2248, ASTME290, F, C and DIN50111 is 14019

Application
Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves.
The stainless steel is used as a bridge, the real frame, fence, ship and vehicle transmission in Construction Engineering.
