Packaging Steel Strip Manufacturers: Brief Introduction to the Structural Composition of Hot-Tinned Steel Strip
　　The hot-dip tinned steel strip is made of high-quality carbon structural steel or ordinary carbon steel, and is mainly used as the outer shield of the coaxial cable.
　　The hot-dip tinned steel for shielding is available in soft and extra soft. According to the steel strip number, its specifications and dimensions are as specified in GB/T 1838-1995.
　　Plating tin should be No. 2 tin. According to the amount of tin plating per 100cm (double-sided) or 200cm? (single-sided) of the steel strip, the tin-plated steel strip is divided into four levels, and the amount of tin plating in each level should meet the requirements of the relevant standards. The surface of the tin-plated steel strip should be smooth and clean, and there should be no cracks, broken edges, burrs, delamination, scales, pits, folds, oil stains, excessive oil film, broadband tin flow, clustered tin accumulation, exposed steel Strips and other defects, allowing slight tin thick edges, tin grains, tin scars, tin bars, tin pits, solvent spots, dark red, ribs, roll marks, ripples, bubbles, scratches, folds, and exposed steel strips Wait. There should be no more than 4 porosity points per 1cm2 for class A and B, and no more than 6 for class C and D.
　　 No. 12-18 tinned steel strip is repeatedly bent at 90° on a repeated bending test machine with a jaw radius of 1.5mm. The extra-soft steel strip is repeatedly bent 8 times, and the mild steel strip is repeatedly bent 6 times. Tinned layer There should be no cracks on the steel base.
