ASME SA336 F5 Forged Steel Tubesheet
ASME SA336 F5 Forged Steel Tubesheet represents a high-performance chromium-molybdenum alloy steel forging designed for critical pressure equipment operating in high-temperature, high-pressure, and corrosive environments.
When heat exchangers or pressure vessels require long-term reliable operation under harsh conditions, selecting forged tube sheets made of SA336 F5 is a very standard and reliable choice.
Advantages
1. Excellent high-temperature strength and creep resistance
2. Superior resistance to hydrogen corrosion
3. Inherent structural integrity and reliability of forgings
4. Excellent combination of mechanical properties
5. Superior machinability and service performance
