A240 321H Stainless Steel Plate: Comprehensive Introduction and Applications

The A240 321H stainless steel plate is a high-performance material widely used across various industries. Its unique combination of mechanical properties, chemical composition, and heat treatment characteristics make it an ideal choice for numerous demanding applications.
Mechanical Properties
The A240 321H stainless steel plate exhibits exceptional mechanical properties. With a tensile strength of 520 MPa and a yield strength of 205 MPa, it offers high resistance to deformation under load. Furthermore, its elongation rate of 40% and reduction of area of 50% demonstrate its excellent ductility and toughness. These properties, coupled with its good weldability, ensure reliable performance in critical applications.
Chemical Composition
The chemical composition of A240 321H stainless steel plate is tailored to provide superior performance. It primarily consists of iron (Fe), chromium (Cr), and nickel (Ni), which contribute to its corrosion resistance and stability. The addition of titanium (Ti) effectively stabilizes the carbide formation, enhancing the weldability and corrosion resistance of the material. Moreover, the higher carbon (C) content in 321H ensures enhanced high-temperature strength and thermal stability.
Heat Treatment
The heat treatment of A240 321H stainless steel plate is crucial to achieve optimal mechanical properties. The solution treatment, which involves heating the material to 920-1150°C and rapid cooling, maximizes corrosion resistance. Additionally, the stabilization treatment, conducted after solution treatment, further enhances the material's resistance to intergranular corrosion. This treatment involves heating the plate to 870-890°C for 2 hours per 25mm thickness, followed by air cooling.
Dimensional Range
The A240 321H stainless steel plate is available in a wide range of dimensions to meet various application requirements. The thickness can vary from 0.1 mm to 300 mm, while the width can extend from 100 mm to 3000 mm. The length of the plate can be customized based on customer specifications. Additionally, the plate is available in various forms, including flat, coiled, and medium-thick plates, offering flexibility in its application.
Impact Testing
The A240 321H stainless steel plate undergoes rigorous impact testing to ensure its resilience and durability. These tests, such as Izod, bending, and Charpy impact tests, assess the material's ability to resist impact loads and determine its toughness and brittleness. The excellent results obtained in these tests validate the plate's suitability for applications requiring high impact resistance.
Primary Applications
The A240 321H stainless steel plate finds applications in numerous industries. In the chemical industry, it is used in the construction of reactors, tanks, and pipelines due to its excellent corrosion resistance. It is also widely used in the oil and gas industry, where its high-temperature strength and corrosion resistance make it ideal for pipelines and other equipment. Furthermore, the plate's aesthetic appeal and durability make it a preferred choice for architectural applications, such as façades and roofing.
