National Standard of PRC Alloy Structure Steels GB/T

The standard will replace GB/T 3077-1988 from the date of the implementation of this standard. The standard was proposed by the State Bureau of Metallurgical Industry. The standard is under the jurisdiction of the National Technical Committee of Standardization Steel.sp.info About - GB/T 3077 Alloy Structure Steel plateThe metal is clamped securely to avoid warping. The steel is then tempered, in order to achieve the desired properties. Quenched and tempered steel is characterised by good ductility and strength, and an extremely fine-grained microstructure.

Steel Plate or structural steel is simply steel sheet material that can be customarily cut and welded to develop a more elaborate product. Steel plate is made by compressing multiple steel layers together into one; forming a plate of steel. Steel Plate is commonly used to strengthen foundations and uphold mass units of weight like bridges.sp.info
