--- title: Zinc-Aluminum-Magnesium Coated Steel Sheet desc: Zinc-Aluminum-Magnesium is a new type of high corrosion resistance coated steel sheet, mainly composed of zinc, plus aluminum, magnesium and trace silicon. Used in construction, home appliances, automotive and other industries. models: - GB/T 38935-2020: Q235 - EN10346-2015: DX51D, S350GD place: Jiaxiang Kelunpu Heavy Industry Co., Ltd. publishedTime: 2023-08-01 images: - /images/product/20251021161717.jpg detail: Textured/Non-textured spec: - 'Thickness: 0.7~6.0mm' - 'Width: 1000~1350mm' packaging: Single coil slug: '1' --- ## Chemical Composition | Grade | C | Mn | Si | P | S | | --- | --- | --- | --- | --- | --- | | Q235 | ≤0.22 | ≤1.40 | ≤0.35 | ≤0.035 | ≤0.035 | | DX51D | ≤0.18 | ≤1.20 | ≤0.5 | ≤0.12 | ≤0.045 | | Q235 | ≤0.2 | ≤1.70 | ≤0.6 | ≤0.045 | ≤0.045 | ## Mechanical Properties | Grade | Yield Strength | Tensile Strength | Elongation After Fracture | Rockwell Hardness | Bending Test | | --- | --- | --- | --- | --- | --- | | Q235 | ≥235 | 370-500 | ≥22 | - | d = 1a | | DX51D | ≥270 | ≥290 | ≥26 | - | d = 0.5a | | S350GD | ≥350 | ≥420 | ≥16 | - | - | 1. When there is no obvious yield, use RP0.2, otherwise use ReL. 2. Sample width B ≥ 20mm, B = 20mm for arbitration; a is sample thickness. 3. Tensile test and bending test take transverse sampling.
