GB/T 2517-1981 Hot Rolled Symbols, Chemical Composition and Mechanical Properties of Steel Plate and Strip for General Structures
GB/T 2517-1981 specifies the symbols, chemical compositions and mechanical properties of hot-rolled steel plates and steel strips used in general structures. All of these steel products are designed to be used for buildings, bridges, ships and similar purposes.
The symbols in this standard specify the type and thickness of the steel plate and steel strip, grade, and purpose. The chemical composition of the steel plate and steel strip is also specified. Chemical composition is expressed in % (m / m) and steel type. The mechanical properties of the steel plate and steel strip includes yield strength, tensile strength, elongation, and reduction of area.
This standard specifies the requirements, the test methods, the inspection rules and the markings, packing, etc., of hot rolled steel plates and steel strips used in general structures. The requirements of this standard are applicable to hot-rolled steel plates and steel strips with a thickness of 2.0-20mm.
This particular standard is an important, vital piece of the regulations and production procedures laid out by Chinas State Bureau of Quality and Technology. It ensures that the hot-rolled steel plates and steel strips used in connected structures are all of the highest quality, and that they are all maintained to a certain standard. This helps to ensure the safety of buildings and other structures relying on these materials, as well as preventing any potential harm from the use of substandard materials. This standard is a necessary part of creating and maintaining robust and reliable construction in China, and elsewhere, and is integral for creating high quality steel plates and steel strips in the country.
This standard keeps the construction industry on the same page with regard to the quality of the steel plates and steel strips used for construction. It has been in effect since 1981, and it has been regularly evaluated and revised to meet the changing needs of businesses and consumers. It is an important cornerstone of materials manufacturing in China, and in its adherence to this standard, the production of construction materials has been greatly improved.
In conclusion, GB/T 2517-1981 is an essential standard that helps ensure the safety and reliability of the hot rolled steel plates and steel strips used in the construction industry by setting out clear standards and expectations for the quality and performance of these materials. It is essential for the production and maintenance of high-quality building materials in China, and its continued enforcement is key for ensuring the highest possible standards are maintained.
