What is Stainless Steel Flat Bar?
Stainless steel flat bar is a rectangular section of steel with a consistent width and thickness, widely used in fabrication, construction, and manufacturing. It is produced either through hot rolling, cold drawing, or cutting from plate, offering versatility and strength.
📐 Standard Dimensions:
Thickness: 2mm – 50mm
Width: 10mm – 500mm
Length: Usually 6 meters, customizable
🔩 Common Grades:
304 / 304L – Excellent corrosion resistance, most popular
316 / 316L – Marine-grade, for harsh environments
430 – Cost-effective, good formability

Product Information of Stainless Steel Flat Steel
Chemical Composition Inspection
(1) Component index: the chemical composition of stainless steel flat steel belongs to the general structure of rolled steel series, the main test indexes for C, Mn, P, S four. According to the content of different grades, each has differences, the approximate scope for C<0.08%, Mn: 0.08 2.0, P < 0.035%, S < 0.03%
(2) inspection method: to test the chemical composition, the standard test methods are GB223, JISG1211-1215, BS1837, BS manual 19, ГОСТ 22536, etc.
The Standard Specifications
GB/T2101-89 (steel acceptance, packing, marking, and general provisions of the quality certificate); / GB9788 GB9787-88-88 (hot rolled size, shape, weight, and allowable deviation); JISG3192-94 (hot rolled steel shape, size, weight, and allow the poor); DIN17100-80 (normal structural steel quality standards); ГОСТ 535-88 (plain carbon steel technical conditions).
According to the prescribed standards, which should have been delivered bales, the strapping passes, with bundle length, should comply with the rules. Generally, without package delivery, transporting and storing all need to be attended to for moistureproofing.
Mechanical Properties Test
(1) tensile test method. Commonly used with GB/T228-87 standard test methods, JISZ2201, JISZ2241, ASTMA370, ГОСТ 1497, BS18, DIN50145, etc.;
(2) the bending test method. Standard test methods with GB/T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ 14019, DIN50111, etc.
(2) performance index, evaluation of the performance of the inspection items are mainly tensile test and bending test. Indexes include the yield point, tensile strength, elongation, bending of qualified, etc.
Stainless Steel Weight Calculation Method
The weight per meter (kg) = 0.00793 * side edge width (mm) thickness (mm)
