ASME SA240 304 Tubesheet Chemical Composition and Mechanical Properties

SA240 SS304 is an austenitic stainless steel grade widely used in heat exchanger applications due to its excellent corrosion resistance, high strength, and superior toughness. Its durability and resistance to oxidation make it ideal for environments with high temperatures and corrosive conditions.

Chemical Composition of SA240 SS304

The high chromium and nickel content provide exceptional resistance to corrosion and oxidation, making SS304 a reliable choice for tubesheets in heat exchangers.

Mechanical Properties of SA240 SS304

These mechanical properties ensure that SA240 SS304 Tubesheets can withstand high pressures and temperatures, as well as mechanical stress, during operation.

Testing Requirements for ASME SA240 304 Tubesheet

To ensure the SA240 SS304 Stainless Steel Tubesheets meet the highest quality standards, we perform comprehensive testing. At Yuhong Holding Group, we employ rigorous inspection methods to verify the material's integrity and ensure its suitability for critical applications.

Key Testing Procedures

1. Penetrant Testing (PT):

   • Detects surface defects such as cracks, pinholes, or porosity.
   • Ensures the surface is free from imperfections that could compromise the tubesheet's performance.

2. Ultrasonic Testing (UT):

   • Identifies subsurface flaws such as inclusions or voids within the material.
   • Ensures the tubesheet meets the required structural integrity standards.

3. Hydrostatic Testing:

   • Simulates operating conditions to verify the tubesheet's ability to withstand high-pressure environments.
   • Ensures no leakage or deformation occurs during operation.

4. Dimensional Inspection:

   • Confirms the precision of drilled holes, surface finish, and overall dimensions.
   • Ensures perfect alignment with heat exchanger tubes.

5. Visual Inspection:

   • Examines the surface for any visible defects or irregularities.
   • Guarantees a smooth and polished finish.

We provide detailed inspection reports for all tests, ensuring full traceability and compliance with international standards.
