Discover SG295 spherical flat steel: Unlock application codes for high-performance steels

Chemical composition of SG295 ball flat steel

Its main components include iron (Fe) as the basic element, carbon (C) content is moderate, generally 0.14%-0.22%, carbon provides basic strength support for steel; Silicon (Si) and manganese (Mn) are added in appropriate amount, silicon helps to improve the strength and hardness of steel, manganese can refine the grain and enhance the toughness, and the two can cooperate to optimize the comprehensive mechanical properties of steel. The content of impurity elements such as phosphorus (P) and sulfur (S) is strictly controlled at a low level to prevent undesirable phenomena such as embrittlement of steel and ensure its stable and reliable quality.

SG295 ball flat steel performance characteristics

Good mechanical properties: It has a high yield strength, usually up to about 295MPa, and the tensile strength is generally in the range of 440MPa-570MPa, which can withstand large tensile, compression and bending loads, providing a solid guarantee for various bearing structures. At the same time, it also has a certain elongation, to ensure that there is enough toughness in the force deformation, to prevent the sudden fracture of the structure, such as Bridges, building support systems and other dynamic load, static load complex conditions outstanding performance.

Corrosion resistance: Although it is not a professional weathering steel or stainless steel, in the general atmospheric environment and freshwater environment, SG295 ball flat steel can resist a certain degree of corrosion and erosion with the oxidation film naturally formed on the surface, maintain the basic integrity of the structure, and the service life can reach several years to decades, depending on the severity of the environment.

SG295 ball flat steel processing properties

Welding performance: Good welding performance, can use common welding methods, such as manual arc welding, gas shielded welding, etc., and suitable welding materials match, can obtain a solid and reliable weld, weld strength is similar to the base metal, to ensure the stable bearing of welded joints in the structure, which is crucial for the assembly and construction of large steel structures.

Cold bending and hot bending performance: It has certain cold bending and hot bending processing capabilities, and can be processed into shapes of different radians and angles according to engineering design requirements, which can be used to build complex curved structures, such as ship's side ribs and the supporting components of building domes, etc., and the internal structural damage of materials is small during processing, and the mechanical properties are basically stable.

SG295 ball flat steel application field

Shipbuilding: It is one of the key materials of ship hull structure, used to manufacture ship bottom keel, side ribs, deck beam and other components, with its good mechanical properties, welding performance and certain corrosion resistance, to ensure the structural strength and safety of the ship in the Marine environment, withstand wind and wave impact, cargo pressure and other external forces.

Bridge engineering: It is widely used in steel beams, bridge panel support beams and other parts of small and medium-sized span Bridges to provide stable horizontal and longitudinal support for Bridges, help Bridges cross rivers, canyons and other obstacles, and withstand the test of long-term vehicle driving vibration and natural environment erosion.

Construction field: It can be used for the roof truss, column support and other structures of large buildings such as industrial plants, exhibition halls and gymnasiums. While meeting the architectural aesthetic design, it ensures the stability and safety of the building space with reliable carrying capacity, and ADAPTS to the complex functional needs of the building.
