ASME SA204 Pressure Vessel Plates | High Quality

What is ASME SA204 Alloy Steel Plates?

ASME SA204 Pressure Vessel Plates (identical with ASTM A204) are typical molybdenum-alloy steel plates intended particularly for welded boilers and other pressure vessels. The steel grades covered by ASTM A204/ ASME SA-204 are all carbon-molybdenum alloy steels with nominal composition of C-0.5Mo. Plates under this standard specification are available in three grades having different strength levels as follows: GRADE A, GRADE B, and GRADE C.

Supply Range of ASME SA204 Pressure Vessel Plates

The maximum thickness of ASTM A204 plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thicknesses of plates made of Grade A, Grade B and Grade C steel to 6″ [150 mm], 6″ [150 mm], 4″ [100 mm], respectively.

The ASTM A204 plates shall be made from killed steels. Plates 1-1/2″ [40 mm] and under in thickness are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved or both. Plates over 1-1/2″ [40 mm] in thickness shall be normalized.

Thickness: 5 MM to 150 MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
Grade : A, B, C

ASTM A204 Pressure Vessel Plates Chemical Composition:

Main chemical composition in ASTM A204 GR A / B / C steel : A204 GR.A Carbon max 0.18, A204GR.B Carbon max 0.20, A204GR.C Carbon max 0.23; Manganese max 0.90, Silicon 0.15-0.40, Phosphorus max 0.035, Sulphur max 0.035 More detailed information, please refer to the flowing table:

ASME SA204 Steel Plates Mechanical Properties

ASTM A204 GR.A / B / C steel grade is a kind of steel which with Cr., Mo., Cr-Mo and mainly used for pressure vessels. The steel grade A204 GR.A / B / C is according to ASTM standard which with the yield strength of 220MPa. The followings are the chemical composition and mechanical properties of ASTM A204 GR.A/B/C steel plate. More detailed information about ASTM A204 GR.A/B/C steel Mechanical Properties, please refer to the following table:

A204 Grade B Alloy Steel Plate Packing

A204 Grade B Alloy Steel Plate sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope. Clear labels tagged on the outside of the package for easy identification of the quantity and product I.D. Great care taken during operation and transportation. A204 Grade B Alloy Steel Plate packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.

Types of Packaging:

– Bundles (hexagonal)
– Wooden Boxes
– Crates (steel/wooden)
– Special crates for U-Bend tubes with each radius separated

Special Features:

Each bundle covered with plastic for protection against extreme weather.
End of A204 Grade B Steel Plate protected by plastic Strip.
Bundles strapped with plastic strips.
Each radius of U-Bend tube separated by a separator.
Packaging list (laminated) placed with box/crate.

ASTM A204 Alloy Steel Plates Application Industries

Besides, this welding-friendly ASTM A204 GRADE B Alloy Steel Plates simplify and speed up the following operations.

Industrial boilers, pressure vessels made from Low Alloy Steel plates like ISOP26 Alloy Steel plates; containing Nickel-Chromium-Molybdenum, they promote heat dissipation not amounting to deformation in their hard surfaces.
ASME SA A204 C Alloy Steel plates are instrumental in building rust free ship hulls and submarines; We made it from fully killed steel, devoid of oxidation, with chromium adding a dash of corrosion proofing from constant contact with sea waters.
Ducting and pipe works, Rail and metal fabricators, automotive and aerospace fabrication, etc. require being hard as nails, with BS 1503-243B Alloy Steel plates providing them with that quality.
Refining and Oil, and Coal and LNG Transportation pipeline networks are erected using ISO TS 26 Alloy Steel plates that manage long distance conveyance of slurries, gases. And inflammable oils through their flushed surfaces, working efficiently at elevated temperatures.

Characteristiacs :

1. High-Temperature Resistant Body

BS243 Alloy Steel Plates unaffected by high temperatures due to their Molybdenum content, creating rock-like bodies. Combustible industries involve high-temperature procedures, where assemblies made from cheap steel can wither away. Alloy Steel sheets mould parts that remain hard enough to promote processes at elevated temperatures.

2. High Strength & Efficiency

Tensile strength of 65-85 ksi gives ASME SA A204 Alloy Steel Plates its identity: the strong potential of being a High Tensile Alloy Steel plate. Annealing, normalizing and tempering create less brittle, more load-bearing plates, steering clear of rust and pitting.

3. Flawless Finish

As suppliers, we furnish EN10028 16Mo3 Alloy Steel plates with excellent surface finishing. The normalizing process reduces the grain sizes, giving clean, even plate surfaces. Their uniform, sleek bodies allow continual flow without shocks at bends and extend an aesthetic look.

4. Longer Life Span

Alloy Steel Plates are robust, recyclable, and have enhanced surface quality. A balance between Steel and chromium forms DIN 15Mo3 Alloy Steel plates imperious to oxidation and erosion, with brittle-free hardenability from Steel and Chromium. They don’t know age or decay, are anti-corrosion and have excellent thermal and heat conductivity. All these factors prove Alloy Steel Coils, Sheets and plates to have a long life, sustainable and viable choice.

Conclusion

IBC (Tianjin) Industrial Co., Ltd is a steel supplier in China, we offer all kinds of alloy pressure vessel steel plate, hot sell ASME SA204 Pressure Vessel Steel Plate. It is a kind of alloy steel material used to fabric high temperature pressure vessels.
