TJC Steel Group is proud to introduce the ASTM A240 309S stainless steel plate, a high-alloy austenitic stainless steel material with exceptional properties that make it a standout choice for numerous industrial applications.

Chemical Composition

The ASTM A240 309S stainless steel plate boasts a well-balanced chemical composition, consisting primarily of chromium (Cr) ranging from 22% to 24%, nickel (Ni) between 12% and 15%, molybdenum (Mo) at approximately 2% to 3%, and a small amount of titanium (Ti) ranging from 0.15% to 0.30%. This composition ensures excellent corrosion resistance, antioxidant properties, and high-temperature endurance.

Mechanical Properties

After solution treatment, the ASTM A240 309S stainless steel plate exhibits remarkable mechanical properties. It has a yield strength of over 205 MPa, a tensile strength exceeding 520 MPa, and an elongation percentage of more than 40%. These properties guarantee stable performance under heavy loads and complex stress conditions.

Heat Treatment Status

The ASTM A240 309S stainless steel plate is typically supplied in a solution-annealed condition, ensuring optimal corrosion resistance and mechanical properties. Heat treatment such as hot rolling and annealing are carefully controlled to maintain the plate's microstructure and ensure its durability.

Size Range

TJC Steel Group offers the ASTM A240 309S stainless steel plate in a wide range of sizes, including 1ft x 4ft, 2ft x 2ft, 2ft x 4ft, 4ft x 4ft, 4ft x 8ft, 4ft x 10ft, and can also provide custom-cut sizes to meet specific project requirements.

Impact Testing

To further validate the ASTM A240 309S stainless steel plate's resilience, it undergoes rigorous impact testing. This testing involves measuring the material's ability to resist deformation and fracture under sudden impacts, ensuring its suitability for applications requiring high toughness and impact resistance.
