In the realm of high-performance steel plates for pressure vessels and boilers, A515 Grade 485/A515Gr.485/A515Gr485 stands as a testament to exceptional quality and reliability. This steel grade, produced by TJC Steel Group, is tailored to meet the stringent requirements of industries where safety and durability are paramount.

Chemical Composition

The chemical composition of A515 Grade 485 steel plate is carefully balanced to ensure optimal mechanical properties. It comprises carbon (C) content not exceeding 0.28%, manganese (Mn) up to 0.90%, phosphorus (P) and sulfur (S) both limited to 0.035% maximum, and silicon (Si) ranging from 0.15% to 0.45%. The addition of chromium (Cr), nickel (Ni), and copper (Cu) in trace amounts further enhances the steel's toughness and corrosion resistance.

Mechanical Properties

A515 Grade 485 steel plate boasts impressive mechanical properties, including a tensile strength ranging from 485 MPa to 620 MPa (70 ksi to 90 ksi) and a yield strength of not less than 415 MPa (60 ksi). These properties, coupled with good ductility and impact resistance, make it ideal for applications that require high-pressure containment.

Heat Treatment Condition

The heat treatment of A515 Grade 485 steel plate is critical to its final properties. Depending on the thickness, the plate may be supplied in either the as-rolled condition or after normalizing. For thicker plates, normalizing is typically performed to ensure uniform microstructure and mechanical properties.

Size Range

A515 Grade 485 steel plate is available in a wide range of sizes to cater to various applications. Standard thicknesses range from 6mm to 120mm, while widths can vary from 1000mm to 4000mm, and lengths from 3000mm to 18000mm. Custom sizes can also be produced to meet specific project requirements.

Impact Test

To ensure the steel plate's ability to withstand sudden loads, A515 Grade 485 undergoes rigorous impact testing. This test measures the plate's energy absorption capacity under impact conditions, ensuring its suitability for demanding applications.

Applications

A515 Grade 485 steel plate finds widespread use in the construction of pressure vessels and boilers in industries such as petrochemicals, power generation, and oil & gas. Its excellent strength-to-weight ratio and corrosion resistance make it a preferred choice for manufacturing reactors, heat exchangers, and other critical components.
