Characteristics of G3103 SB42 Steel Plate
Mechanical Properties
Yield Strength: Typically not less than 225MPa, indicating that the SB42 steel plate can maintain good shape stability when subjected to external forces.
Tensile Strength: Ranges from 410MPa to 550MPa, demonstrating a high level of strength suitable for applications requiring the bearing of significant loads.
Elongation: Not less than 21%, meaning the SB42 steel plate can undergo substantial plastic deformation without easily fracturing under stress, exhibiting good toughness.
Physical Properties
Elastic Modulus: Between 190GPa and 210GPa, reflecting the steel's ability to resist elastic deformation when subjected to force.
Density: Between 7.67kg/dm³ and 7.86kg/dm³, similar to that of ordinary steel.
Poisson's Ratio: Between 0.27 and 0.3, describing the ratio of transverse strain to longitudinal strain in the steel when subjected to force.
Application Characteristics
Boiler and Pressure Vessel Manufacturing: The SB42 steel plate is widely used in the manufacturing of boilers and pressure vessels due to its excellent mechanical properties and chemical composition. These devices need to withstand harsh conditions such as high temperatures and pressures, thus requiring steel with high strength and toughness.
Petrochemical and Manufacturing Industries: In the petrochemical and manufacturing industries, the SB42 steel plate is also commonly used to manufacture various equipment and pipelines. These industries have high requirements for the corrosion resistance and high-temperature performance of steel, and the SB42 steel plate can meet these demands.
