25Mn high quality carbon structural steel

25Mn Carbon Structural Steel

25Mn carbon structural steel has relatively high plasticity, good formability and good welding performance. It is usually selected to produce structural parts by welding, bolting or riveting. 25Mn carbon structural steel is suitable for the manufacture of various structural parts and components requiring good toughness and wear resistance, such as axle shafts, bridges, rods and so on.

25Mn carbon structural steel is a low-alloy steel grade of carbon structural steel. The chemical composition of this steel grade is as follows: 25Mn carbon structural steel is composed of 0.25% carbon, 0.0% to 0.4% Si, 1.4% Mn, 0.0% P, 0.0% S, 0.05% to 0.2% Cr, 0.03% Nb, and the balance Fe.

The mechanical properties of 25Mn carbon structural steel are as follows: the yield strength is 250MPa and the tensile strength is 600MPa. The elongation of 25Mn carbon structural steel after fracture is over 17.5%. The impact toughness of 25Mn carbon structural steel is favorable, and its Brinell hardness is 200HB.

In addition, 25Mn carbon structural steel work hardens during cold working, so it needs to be annealed to reduce mechanical strength and restore plasticity and ductility. 25Mn carbon structural steel has good machinability.

25Mn carbon structural steel has strong anti-oxidation properties, and its anti-oxidation performance also conforms to the requirements of the GB standard. It is mainly used to obtain high strength and wear resistance after quenching and tempering. It is mainly used in the production of tools and dies, as well as the fasteners used in high temperature and corrosion environment. 25Mn carbon structural steel can also be used to make the parts of blowers, steam turbines and other components that require high toughness and high strength.

In summary, 25Mn carbon structural steel is a kind of high-strength low-alloy steel which is easy to form and process. It has good weldability and low temperature impact toughness. In addition, its oxidation resistance is good and it is an economical steel grade suitable for the manufacture of various structural parts and components.
