Our plates are produced in accordance with the highest industry standards, ensuring reliability and durability in various demanding environments.

Chemical Composition:

The A240 439 stainless steel plate is composed of a unique blend of elements that contribute to its exceptional properties. The primary chemical composition includes chromium (Cr) ranging from 17% to 19%, molybdenum (Mo) at 0.75%, titanium (Ti) or niobium (Nb) between 0.30% and 0.60%, and the balance comprising iron (Fe) and trace elements such as phosphorus (P) and nitrogen (N). This composition ensures excellent corrosion resistance and high-temperature performance.

Mechanical Properties:

Our A240 439 stainless steel plate possesses impressive mechanical properties. It exhibits a tensile strength of at least 415 N/mm² and a yield strength of 205 N/mm² or higher, according to ASTM standards. It also maintains a ductility of 22% or more, ensuring ease of forming and welding. The hardness of this material, measured in HV, is typically 180 or less, contributing to its versatility in a wide range of applications.

Heat Treatment State:

The A240 439 stainless steel plate is typically supplied in an annealed condition, ensuring optimal ductility and formability. Annealing involves heating the material to a specific temperature and then slowly cooling it to relieve internal stresses and improve the overall mechanical properties. This process ensures that our plates are ready for further processing and fabrication.

Size Range:

TJC Steel Group offers A240 439 stainless steel plates in a wide range of sizes to meet the diverse needs of our customers. The plates are available in thicknesses ranging from 0.12mm to 65mm, with standard widths of 1000mm2000mm, 1219mm2438mm, and other custom dimensions. We can also provide cut-to-size plates based on specific requirements.

Impact Testing:

The A240 439 stainless steel plate undergoes rigorous impact testing to ensure its ability to withstand sudden and severe impacts. This testing involves subjecting the material to a controlled impact force and measuring its resistance to deformation and fracture. Our plates demonstrate excellent impact resistance, ensuring their reliability in applications where impact loads are a concern.

Main Application Scenarios:

The A240 439 stainless steel plate finds applications in various industries due to its exceptional properties. It is commonly used in automotive exhaust systems, where its corrosion resistance and high-temperature performance are crucial. It is also utilized in chemical industry equipment, gas water heaters, home appliances, and construction materials, such as elevator and escalator decorative panels.
