ASME SA336 F11 Cl2 Stationary Tubesheet For Nuclear Power Heat Exchanger Tube Sheet
ASME SA336 F11 CL2 high-temperature alloy steel tubesheets are core pressure-bearing components of shell-and-tube heat exchangers designed for extreme high-temperature, high-pressure, and hydrogen-corrosive environments.
Made from chromium-molybdenum alloy steel forgings (1.0-1.5% Cr, 0.44-0.65% Mo), heat-treated to ensure high strength and toughness even at temperatures ≤595°C.
This material resists high-temperature hydrogen corrosion and is suitable for demanding applications such as hydrogenation reactors, nuclear steam generators, and thermal power plant high-pressure feedwater heaters. Compared to carbon steel tubesheets, its high-temperature strength retention is 40% higher, and controlled hardness effectively suppresses wet H₂S stress corrosion cracking.
Typical applications include refinery 15MPa-rated reaction effluent heat exchangers, thermal power plant feedwater systems subject to temperature swings exceeding 150°C, and waste heat boilers in ammonia synthesis plants.
