GB/T 700 is China's national standard for steel, defining the grades, properties, manufacturing, and testing of carbon and low-alloy steel products. The standard ensures that all steel has the same properties and requirements, regardless of source, providing a reliable and unified method of steel production and use. GB/T 700 U12152 is regularly used in the manufacture and application of steel products, including shipbuilding, welded pipes, automobiles, and construction. Its implementation is necessary for the safe, efficient, and durable construction of products across China and the world.

Toughness of a material refers to its ability to absorb energy and deform without experiencing catastrophic failure. It is measured using a toughness test, which typically involves applying an impact force to a sample of material until it fails. Generally, the toughness of GB/T 700 Q235C steel can reach up to 3.2J.

GB/T 700 Q275B steel is an all-round steel used for various metal constructions in China. It has excellent mechanical properties, including yield strength, tensile strength, toughness, elongation, and even overall ductility.

GB/T 700 is the standard set by the Chinese government to standardize steel grades. Established in 2010, the GB/T 700 standard establishes the classification, characteristics, and requirements of carbon and low-alloy steels. It stipulates requirements for all aspects of steel production, including chemical composition, mechanical, metallurgical, physical, and special tests and quality control. GB/T 700 helps to ensure that all steel products meet the same standards regardless of their source.

The yield strength of GB/T 700 Q235B steel is the amount of force that must be applied to it before it starts to yield or deform plastically. Yield strength is also referred to as the yield point or yield limit. It is measured using a yield strength test, which typically involves applying a longitudinal tensile force to a sample of material until it starts to yield or deform plastically. Generally, the yield strength of GB/T 700 Q235B steel can reach up to 300MPa.

The main characteristics of GB/T 700 U11952 carbon structural steel are its high strength, good ductility, and low cost. It has a high tensile strength of up to 745 Mpa, making it a good choice for structural applications where a large load-bearing capacity is needed. It has good weldability, allowing for easy fabrication of steel components, and it exhibits good formability which allows for easy assembly and shaping of parts. Its low cost is attributed to its large circulation in the Chinese market.

The thermal properties of GB/T 700 U12359 steel depend on the composition and treatment of the material. The thermal conductivity of GB/T 700 U12359 steel is 59–73 W/mK, depending on the material grade, while the thermal diffusivity is 3–7.5 mm2/s. The thermal expansions of these steels range from 11.0–14.5 μm/m℃. In general, GB/T 700 U12359 steels are considered to have very good thermal properties.

The main characteristics of GB/T 700 Q275D carbon structural steel are its high strength, good ductility, and low cost. It has a high tensile strength of up to 745 Mpa, making it a good choice for structural applications where a large load-bearing capacity is needed. It has good weldability, allowing for easy fabrication of steel components, and it exhibits good formability which allows for easy assembly and shaping of parts. Its low cost is attributed to its large circulation in the Chinese market.

GB/T 700 U12758 carbon structural steel is a series of low-carbon steels that have been developed for a variety of industrial applications. Its goal is to provide a high grade of strength, improved weldability and formability, and better cost efficiency. GB/T 700 U12758s are typically used in applications such as bridges, roads, sailboats, and buildings.
