ASME SA240 SS321 Bottom Head
The ASME SA240 SS321 bottom head is a type of pressure vessel component made from stainless steel grade 321. It is designed to be used at the bottom of a pressure vessel to provide structural support and containment for the contents inside. The ASME SA240 specification ensures that the bottom head meets the standards set by the American Society of Mechanical Engineers for material composition, mechanical properties, and fabrication methods. Stainless steel grade 321 is known for its excellent corrosion resistance, high temperature strength, and weldability, making it a popular choice for pressure vessel applications. The bottom head is typically manufactured using hot forming or cold forming processes to achieve the desired shape and dimensions required for the specific pressure vessel design.
