Why Choose A/SA182 F304H Stainless Steel Flanges

A/SA182 F304H is widely used in refineries, power plants, and petrochemical facilities due to its enhanced high-temperature strength compared with standard 304 grades.
Key advantages include:

• Excellent mechanical stability at elevated temperatures
• Good corrosion resistance in industrial environments
• Reliable weldability for weld neck flange connections
• Full compliance with ASME B16.5 dimensional tolerances

These characteristics make F304H Class 600 flanges suitable for demanding pressure and temperature applications.

Quality Control and Delivery Assurance

For this Malaysia project, Haihao Group applied strict quality control procedures, including:

• Raw material certification and traceability
• Dimensional inspection of flange faces and hubs
• Visual inspection of raised face sealing surfaces
