ASME SA832 Grade 22V Steel Plate | SA832 Gr.22V Cr-Mo-V Vessel Plate

ASME SA832 Grade 22V, also written ASME SA832 GR.22V, is chromium-molybdenum-vanadium alloy plate under ASME SA-832/SA-832M. The specification covers three grades only: 21V, 22V and 23V. Grade 22V is the 2.25Cr-1Mo-V line. Chromium heat is 2.00–2.50%. Molybdenum heat is 0.90–1.10%. Vanadium heat is 0.25–0.35%. The plates are required to be normalized and tempered. Quenched-and-tempered Cr-Mo-V of this family belongs to SA-542 / A542, not this page. As Direct Mill Supply by SHH STEEL, the plate is produced to ASME SA-832/SA-832M.

Buyers write ASME SA832 Grade 22V, ASME SA832 GR.22V, SA832 Grade 22V, SA832 22V, SA832GR22V, SA-832 Grade 22V and SA 832 Gr 22V. ASTM A832 Grade 22V is the companion product spec. There is no Class and no Type. A purchase order that says “SA832 Grade 22” without the V is mixing this book with SA387 Gr.22 Cl.2.

This page is not SA387 Grade 22. SA387 Grade 22 is 2.25Cr-1Mo without the vanadium band that defines 22V. It is not SA517 Gr.F. It is not SA841 TMCP. It is not ASME SA516 carbon plate. Thickness is limited only by the ability of the composition to meet the tensile table after normalize and temper.

Minimum normalizing temperature for Grade 22V is 900 °C. Minimum tempering temperature is 675 °C. Grade 23V uses a higher normalizing floor. Dual marking SA832 / A832 Grade 22V is available. Certificates can be EN 10204 3.1 or 3.2. Company scope: China steel Mill Agent-SHH STEEL.

This plate sits in the pressure vessel steel plates family and with ASME SA387 as a related Cr-Mo family, not as a substitute. It does not sit with carbon steel plates or ASTM A36/A36M.

SA-20 still governs marking, testing location, retests and repair rules.

ASME SA832 Grade 22V / ASME SA832 GR.22V has its own heat and product columns. Grade 21V and Grade 23V use a higher chromium band.

Heat Analysis and Product Analysis — ASME SA832 Grade 22V

Vanadium is not optional decoration. If V is missing, the plate is closer to SA387 Grade 22 than to SA832 22V. Chromium at 2.75–3.25% is Grade 21V or Grade 23V, not Grade 22V.

SHH STEEL reports heat analysis on every certificate, including Cr, Mo and V, and product analysis when SA-20 requires it.

All three SA832 grades share one tensile table. The Grade letter changes chemistry and normalizing floor, not the published tensile numbers.

Tensile Requirements — ASME SA832 Grade 22V

Density is 7.85 g/cm³. Notch toughness is commonly added for reactor work. Write the temperature, energy, location and orientation. Simulated PWHT is common because these plates often go into vessels that will see a long shop cycle.

Do not treat 415 MPa yield as permission to substitute SA516 Gr.70, SA533 Type B Class 1 or high strength low alloy plates.

SA299 Gr.B, SA225 Gr.D, SA455 and SA285 Gr.C are also vessel plates. None of them is ASME SA832 GR.22V.

ASME SA832 Grade 22V / ASME SA832 GR.22V is selected when the vessel wants normalized-and-tempered 2.25Cr-1Mo-V. Typical equipment is high-temperature welded pressure vessels, including hydroprocessing and other Cr-Mo-V reactor work written to SA-832 Grade 22V. Allowable stress comes from ASME Section II Part D after the Code lists this Grade.

It is not nickel low-temp plate like SA203 Gr.D. It is not layered QT carbon like SA724. Stainless inquiries belong on ASME SA240/SA240M, ASTM A240/A240M or stainless steel sheets and plates.

Do not form this plate as if it were as-rolled carbon. Normalize-and-temper properties are the product. A later PWHT cycle has to be planned and, when required, simulated on coupons.

SA832 22V is killed, fine-grain Cr-Mo-V. Welding is Code welding.

Qualify procedures to ASME Section IX. Use consumables written for 2.25Cr-1Mo-V, not a plain carbon procedure and not an unreviewed SA387 Grade 22 procedure. Vanadium and the N+T condition belong in the WPS review. Hydrogen control, preheat, interpass and PWHT follow the qualified procedure and the vessel specification.

Do not copy a SA387 Gr.12 Cl.2 procedure onto 22V without review. The fabricator owns the WPS.

All plates shall be normalized and tempered, except as the specification allows otherwise. For Grade 22V the minimum normalizing temperature is 900 °C (1650 °F). The minimum tempering temperature is 675 °C (1250 °F). Grade 23V uses a higher normalizing floor of 1010 °C. Do not apply the 23V floor to 22V without checking the order, and do not quench-and-temper this plate and still stamp SA832.

If the vessel will see a long PWHT, test coupons shall follow a simulated cycle. This is not the TMCP route and not the SA542 QT route. SHH STEEL prints N+T, Grade 22V, normalizing temperature and tempering temperature on the certificate when the mill record carries them.

Usual delivery is normalized-and-tempered ASME SA832 Grade 22V / ASME SA832 GR.22V plate.

The certificate lists ASME SA832 Grade 22V and, when dual certified, ASTM A832 Grade 22V; heat number; heat analysis including Cr, Mo and V; product analysis when ordered; tensile results; N+T statement; impact and simulated PWHT when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for SA832 22V Cr-Mo-V vessel plate:

• Thickness: commonly 8 mm – 150 mm, limited by the ability of the heat to meet 415 MPa yield after N+T
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm
• Cut-to-length shells, heads and nest sizes inside those limits

Structural sizes belong on EN 10025-2 or JIS G3106. Weathering plate belongs on EN 10025-5 or Corten A/B. Fine-grain structural belongs on EN 10025-3 or EN 10025-4. QT structural belongs on EN 10025-6.

Dimensional limits follow ASME SA-20. Thickness, width, length, flatness and camber are vessel-plate tolerances. UT to A435 / A577 / A578 is commonly added on reactor plate.

Most export ASME SA832 Grade 22V / ASME SA832 GR.22V orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation.

Simulated PWHT. Same-heat coupons follow the vessel cycle.

NDE. UT to A435 / A577 / A578.

Hydrogen-service extras. When the vessel specification names them.

Third-party. EN 10204 3.2.

DIN 17100, ASTM A516, ASME SA515 and ASTM A285 are not SA832 22V.

Ship plate inquiries belong on shipbuilding steel plates or BV Rules. Weathering inquiries belong on weathering steel plates. Stainless inquiries belong on stainless steel products, JIS G4305 or AISI stainless.

Other vessel comparisons: SA203 Gr.B, SA302 Gr.C, A516 Gr.70, SA533 Type C Class 2, SA517 Gr.P.

SHH STEEL works as a China Mill Direct Exporter for plates to ASME SA-832/SA-832M. On ASME SA832 Grade 22V / ASME SA832 GR.22V that means mill pricing, dual SA832/A832 marking, Grade 22V chemistry with Cr-Mo-V reported, recorded normalize and temper at the Grade 22V floors, tensile results at 415 MPa yield and 585–760 MPa tensile, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. 22V is not 21V and is not 23V. SA832 is not SA387 Grade 22. SA832 is not SA516 Gr.55. SA832 22V is not SA533 Type C Class 1. If the drawing names QT Cr-Mo-V, we point the inquiry to SA542. If the shop plans as-rolled delivery, we will say this specification is N+T.
