24 Gauge 304 Prepainted Sheet Coils Stainless Steel Pained PVDF Coil Corrosion Resistance
Advantages of 304 stainless steel painted coil
Long service life at least 30 years, good corrosion and rust prevention, and high recycling rate. high strength.
Color coating technology solves the problems of light pollution, galvanic corrosion and chloride ion corrosion of stainless steel 2B plate, and increases the corrosion resistance of stainless steel 2B plate. Color coating has a harmonious appearance indicating effect and friendly visual effect.
304 stainless steel painted coils have become a new generation of metal roofing materials after galvanized profiled steel sheets and aluminum alloy roof panels.
304 stainless steel painted coil is a universal stainless steel material with the following chemical composition:
| Chemical Composition | C | Si | Mn | P | S | Cr | Ni |
| Standard Value | 0.03-0.08% | ≤ 1% | ≤2% | ≤0.05% | ≤0.03% | 18 - 20% | 8-11% |
304 stainless steel painted coil has stronger anti-rust performance than 200 series stainless steel materials.
304 stainless steel painted coil has excellent stainless corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration ≤ 65% below the boiling temperature.
Also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. Steel number: 0Cr18Ni9, density: 7.93 g/cm3, physical properties: tensile strength σb (MPa) ≥ 520, conditional yield strength σ 0.2 (MPa) ≥ 205, elongation δ 5 (%) ≥ 40, section shrinkage Rate ψ (%)≥60, hardness: HB≤187; HRB≤90; HV ≤200.
