Advantages and Characteristics of G3115 SPV36 Steel Plate
High Strength and Excellent Toughness
The SPV36 steel plate boasts a yield strength of ≥355MPa and a tensile strength ranging from 490-630MPa, enabling it to withstand high loads in high-pressure equipment. Its outstanding low-temperature toughness ensures an impact energy of ≥27J at -40°C, guaranteeing stable performance in cold regions or low-temperature operating conditions. This balance of strength and toughness makes it suitable for applications requiring simultaneous resistance to pressure and temperature fluctuations.
Superior Weldability and Machinability
With a carbon content controlled at ≤0.22% and a well-optimized combination of manganese (Mn), silicon (Si), and other elements, the steel plate significantly reduces the risk of welding cracks. It supports various welding methods, including Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding (MIG/MAG), ensuring stable weld quality. Additionally, it can be processed into complex shapes through rolling, stamping, cutting, and other techniques, meeting customized requirements for pressure vessels, pipelines, and other equipment.
Corrosion Resistance and Environmental Adaptability
The addition of alloy elements such as copper (Cu), nickel (Ni), and chromium (Cr) forms a dense oxide film, effectively resisting erosion from atmospheric conditions, water vapor, and mildly corrosive media. In humid or industrial atmospheric environments, its corrosion resistance is 2-5 times that of ordinary carbon steel, extending equipment service life and reducing maintenance costs.
