GB/T1591-1994 High Strength Low Alloy Structural Steel Standard
The GB/T1591-1994 high strength low alloy structural steel standard is a national standard in China which specifies the requirements for the chemical composition, mechanical properties and general technical requirements for the production of high strength low alloy structural steel.
The GB/T1591-1994 high strength low alloy structural steel standard lays down the requirements for the chemical composition of the steel. In this respect, the content of elements such as carbon, phosphorus, sulfur, vanadium and titanium are regulated. Depending on the application, special grades of steel are required with greater values of certain trace elements such as chromium, molybdenum or niobium or manganese.
The mechanical properties of the steel is also specified by the the GB/T1591-1994 standards. The tensile strength, yield strength and elongation properties required for a particular application are specified. Depending on the application, a steel grade is chosen whose mechanical properties satisfied the desired requirements.
The standard also specifies general technical requirements for the manufacture of the high strength low alloy structural steel. These include the manufacturing process, test methods, inspection rules, packing and marking and other necessary information concerning the production of the high strength low alloy structural steel.
The implementation of the GB/T1591-1994 high strength low alloy standard has led to improved manufacturing processes and better steel qualities. The standard has enabled the Chinese industry to meet all the requirements for modern high strength low alloy steel production. The standard is the cornerstone for the production of high quality steel products in China.
