Grades: ASTM A182 F11, F22, F91 & ASTM A350 LF2
Inox Steel India is a trusted manufacturer, supplier, and exporter of Pressure Vessel Components, supplying forged and machined components in ASTM A182 F11, F22, F91 (Cr-Mo alloy steels) and ASTM A350 LF2 (low-temperature carbon steel) for critical pressure applications across India, GCC, Middle East, Africa, Europe, and the Americas.
Pressure vessel components operate under high internal pressure, extreme temperatures, cyclic loading, and corrosive environments. Material selection, forging quality, and heat treatment are therefore critical for ensuring long-term safety, compliance with ASME codes, and reliable plant operation.
At Inox Steel India, pressure vessel components are manufactured through controlled forging, precise heat treatment, and application-specific machining, fully aligned with ASME Boiler & Pressure Vessel Code (BPVC) requirements.
Pressure vessel components are load-bearing parts used in vessels and equipment designed to contain gases or liquids at pressures significantly different from ambient pressure. These components form the primary pressure boundary and must withstand:
Typical pressure vessel components include forged flanges, nozzles, tube sheets, rings, heads, shell components, and machined blocks, all manufactured to strict dimensional and metallurgical standards.
These grades are specifically selected for their strength, temperature resistance, and toughness, depending on service conditions.
🔹 ASTM A182 F11 (1.25Cr–0.5Mo)
Used for moderate high-temperature pressure service, offering good creep resistance and weldability.
🔹 ASTM A182 F22 (2.25Cr–1Mo)
Preferred for higher temperature and pressure applications, such as reactors and boilers, due to enhanced creep strength.
🔹 ASTM A182 F91 (9Cr–1Mo–V)
Used in very high-temperature and high-pressure service, including power plant boilers and superheaters, where long-term creep resistance is critical.
🔹 ASTM A350 LF2
A low-temperature carbon steel grade used for cryogenic and sub-zero pressure service, offering excellent impact toughness at low temperatures.
