Product Information: 304H Stainless Steel Plate
1. Material Grade:
304H Stainless Steel (UNS S30409, ASTM A240/A240M, ASME SA-240)
2. Overview:
304H is a high-carbon variation of the classic 304 austenitic stainless steel, specifically designed for enhanced strength and creep resistance at elevated temperatures (typically above 500°C / 932°F). The "H" denotes higher carbon content (0.04–0.10%), which stabilizes the structure against sensitization and ensures superior performance in high-heat applications like pressure vessels, boilers, and heat exchangers. It retains excellent corrosion resistance, formability, and weldability.
3. Key Features & Benefits:
-
High-Temperature Strength: Optimized for sustained service up to 815°C (1500°F).
-
Creep Resistance: Minimizes deformation under mechanical stress at elevated temperatures.
-
Corrosion Resistance: Resists oxidation, scaling, and general corrosion in acidic/caustic environments.
-
Austenitic Structure: Non-magnetic, ductile, and easy to fabricate/weld.
-
H-Grade Compliance: Meets ASME Boiler and Pressure Vessel Code requirements for high-temperature use.
4. Chemical Composition (Typical % Weight):
| Element | Carbon (C) | Chromium (Cr) | Nickel (Ni) | Manganese (Mn) | Silicon (Si) | Phosphorus (P) | Sulfur (S) | Iron (Fe) |
|---|---|---|---|---|---|---|---|---|
| Content | 0.04–0.10 | 18.0–20.0 | 8.0–10.5 | ≤2.0 | ≤0.75 | ≤0.045 | ≤0.030 | Balance |
5. Mechanical Properties (Room Temperature):
-
Tensile Strength: ≥515 MPa (75 ksi)
-
Yield Strength (0.2% Offset): ≥205 MPa (30 ksi)
-
Elongation: ≥40% (in 50mm)
-
Hardness (Brinell): ≤201 HB
-
Density: 8.0 g/cm³
6. High-Temperature Performance:
-
Max Continuous Service Temp: 870°C (1600°F)
-
Max Intermittent Service Temp: 925°C (1700°F)
7. Available Forms & Dimensions:
-
Thickness: 3mm – 100mm (Custom sizes available)
-
Width: 1000mm, 1219mm (48"), 1500mm, 2000mm (Custom widths)
-
Length: 2000mm, 2438mm (96"), 3000mm, 6000mm (Custom lengths)
-
Form: Hot-Rolled (HR) or Cold-Rolled (CR) Plates
8. Surface Finishes:
-
Hot-Rolled: No.1, Scale-Free Annealed
-
Cold-Rolled: 2B (Standard Bright), BA (Mirror Bright), No.4 (Brushed), HL (Hairline)
-
Special: Pickled, Passivated, Sandblasted
9. Standards & Certifications:
-
ASTM A240/A240M, ASME SA-240
-
EN 10028-7: X6CrNi18-10
-
ISO 9445, JIS G4304
-
Material Test Certificates (MTC) per EN 10204 3.1/3.2
10. Applications:
-
Boiler & Pressure Vessel Components
-
Heat Exchangers & Condensers
-
High-Temperature Pipelines & Valves
-
Power Generation Systems (Gas Turbines)
-
Chemical Processing Equipment
-
Furnace Parts & Heat Treatment Fixtures
11. Fabrication Notes:
-
Welding: Use 308H or 347 filler metal; pre/post-weld heat treatment not typically required.
-
Machining: Low work-hardening rate allows good machinability (use sharp tools + coolants).
-
Forming: Excellent ductility supports bending, stamping, and deep drawing.
12. Packaging:
-
Wooden crates/pallets with waterproof wrapping.
-
Edge protectors and anti-rust paper for corrosion prevention.
Why Choose 304H Plate?
Ideal for critical applications demanding heat resistance + corrosion protection, 304H delivers unmatched reliability in extreme conditions. Its controlled carbon content prevents carbide precipitation during welding/heat exposure, ensuring long-term structural integrity.
Customization Options:
-
Precision cutting (waterjet, laser, plasma)
-
Beveled edges for welding
-
Non-standard dimensions & finishes
