ASTM B928/ASTM B928M is a standard specification for sheet and plate of high magnesium aluminum alloy for marine and similar environments, published by the United States Society for Testing and Materials (ASTM). Here’s a closer look at the standard: 1. Overview of the standard Standard number: ASTM B928/ASTM B928M Second, the main requirements Scope of application The standard covers high-magnesium aluminum alloy sheets and plates for use in marine and similar environments, such as marine applications where there is frequent or continuous direct contact with seawater. These products are mainly used in hull structures and other applications that require high corrosion resistance. Alloys & Status The standard details the applicable alloy states and models, which typically contain 3% or more nominal magnesium to improve their corrosion resistance. The alloy and state names are in accordance with the ANSI H35.1/H35.1M standard, and the equivalent Harmonized Numbering System alloy names are the names in Table 1 with A9 in front, e.g. A95083 for alloy 5083. Units Both SI units (in meters) and inches-pound units are provided in the standard, but the values specified in each system should be considered as separate standards and should not be mixed with performance requirements This standard puts forward specific requirements for the chemical composition, heat treatment, tensile properties, bending properties, stress corrosion resistance, peel corrosion resistance and other properties of the product. Manufacturers need to carry out production and quality control in accordance with the requirements of the standard to ensure that the products meet the specified performance indicators. Delivery status The products are usually delivered in a finished rolling condition and are suitable for different forms such as flat plates, coils and plates. Third, the field of application ASTM B928/ASTM B928M is a standard specification for high-magnesium aluminum alloy sheets and plates for marine and similar environments, which are widely used in various fields, such as: Nautical field marine engineering, etc 4. Precautions When using high-magnesium aluminum alloy sheets and plates, users should fully understand the performance and characteristics of the product, and install and use them in accordance with the standard requirements. Due to the particularity of navigation and similar environments, the product may be eroded by corrosive media such as seawater and salt spray during use, so special attention needs to be paid to the anti-corrosion measures and regular maintenance of the product. In summary, ASTM B928/ASTM B928M is an important standard specification for high magnesium aluminum alloy sheets and plates for marine and similar environments, which provides users with detailed product requirements and performance indicators to ensure the quality and reliability of the products.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
