A515 Grade 485 Pressure Vessel and Boiler Steel Plate

​In the world of steel materials, A515 Grade 485 steel plate stands out as a reliable and robust choice for pressure vessel and boiler applications. This high-performance steel grade, known also as A515Gr.485 or A515Gr485, is tailored to meet the demanding requirements of various industrial applications.
Chemical Composition
The chemical composition of A515 Grade 485 steel plate is carefully controlled to ensure optimal mechanical properties. The carbon (C) content ranges from 0.25mm to 0.31% for thicknesses up to 200mm, ensuring excellent strength and ductility. The manganese (Mn) content is limited to 0.90% maximum, while the phosphorus (P) and sulfur (S) contents are restricted to 0.035% each to guarantee high corrosion resistance. Silicon (Si) content ranges from 0.15% to 0.40%, contributing to the steel's overall mechanical behavior.
Mechanical Properties
A515 Grade 485 steel plate exhibits superior mechanical properties, including a minimum tensile strength of 485 MPa (70 ksi) and a yield strength ranging from 310 MPa (45 ksi) to 415 MPa (60 ksi). The steel's elongation is also noteworthy, ensuring ductility and resilience under various loading conditions.
Heat Treatment Condition
A515 Grade 485 steel plate is typically supplied in a normalized condition, which involves heating the steel to a specific temperature and then allowing it to cool in air. This heat treatment process enhances the steel's mechanical properties, making it suitable for demanding applications.
Size Range
TJC Steel Group offers A515 Grade 485 steel plate in a wide range of sizes to meet various customer requirements. The standard thickness ranges from 6mm to 120mm, while the width can be customized from 1000mm to 4000mm. The length of the plate can be tailored to meet specific project demands, with a maximum length of 18000mm.
Impact Testing
A515 Grade 485 steel plate undergoes rigorous impact testing to ensure its resistance to low-temperature brittleness. The steel is tested at various temperatures, including -20°C, to assess its ability to maintain structural integrity under extreme conditions.
Main Application Scenarios
A515 Grade 485 steel plate finds widespread application in the manufacturing of pressure vessels and boilers. It is used in various industries, including chemical, petrochemical, power generation, and oil and gas, where the steel's excellent strength, ductility, and corrosion resistance are paramount.
