ASTM A240 348 and 348H stainless steel plates are high-performance austenitic stainless steels, primarily designed for elevated-temperature applications where resistance to intergranular corrosion and creep is critical. Our plates are available in standard widths of 1250mm and 1500mm, with customizable lengths, and can be precision-cut via laser to meet specific project requirements.
Chemical Composition (Typical, %)
The chemical makeup of 348 and 348H stainless steel is tailored to enhance high-temperature stability and corrosion resistance:
| Element | 348 (ASTM A240) | 348H (ASTM A240) |
|---|---|---|
| Carbon (C) | 0.08 max | 0.04 – 0.10 |
| Chromium (Cr) | 17.0 – 19.0 | 17.0 – 19.0 |
| Nickel (Ni) | 9.0 – 13.0 | 9.0 – 13.0 |
| Niobium (Nb) | 10×C min (0.70 min) | 10×C min (0.70 min) |
| Titanium (Ti) | 0.10 max | 0.10 max |
| Manganese (Mn) | 2.00 max | 2.00 max |
| Silicon (Si) | 0.75 max | 0.75 max |
| Phosphorus (P) | 0.045 max | 0.045 max |
| Sulfur (S) | 0.030 max | 0.030 max |
| Nitrogen (N) | 0.10 max | 0.10 max |
Note: 348H has a higher carbon content than 348, enhancing its strength at elevated temperatures.
Mechanical Properties
ASTM A240 348 and 348H stainless steel plates exhibit excellent mechanical performance, especially under high-temperature conditions:
| Property | 348 (Room Temperature) | 348H (Room Temperature) |
|---|---|---|
| Tensile Strength | ≥ 515 MPa (75 ksi) | ≥ 515 MPa (75 ksi) |
| Yield Strength (0.2% offset) | ≥ 205 MPa (30 ksi) | ≥ 205 MPa (30 ksi) |
| Elongation (in 50mm) | ≥ 40% | ≥ 40% |
| Hardness (Brinell) | ≤ 217 HB | ≤ 217 HB |
Product Standards
Our 348 and 348H stainless steel plates are manufactured in strict compliance with international standards to ensure quality and consistency:
- ASTM A240 / ASME SA240: Primary standard for chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and general applications.
- ASTM A480: Specifies tolerances for plate, sheet, and strip.
Equivalent Grades
348 stainless steel is recognized by the following equivalent designations globally:
- UNS: S34800 (348); S34809 (348H)
- EN: 1.4548
- DIN: X6CrNiNb18-10
- JIS: SUS348
- GB/T: 06Cr18Ni11Nb
Product Features
- High-Temperature Resistance: Exceptional creep strength and oxidation resistance at temperatures up to 800°C (1472°F), making it ideal for high-heat environments.
- Intergranular Corrosion Resistance: Stabilized with niobium (Nb) to prevent chromium carbide precipitation, eliminating sensitization and enhancing resistance to intergranular corrosion (e.g., in chloride or acidic environments).
- Austenitic Structure: Non-magnetic, with excellent ductility and formability, allowing for easy fabrication (welding, bending, cutting).
- 348H Variant: Higher carbon content in 348H improves high-temperature strength, making it preferred for critical pressure vessel and boiler applications.
- Consistent Quality: Manufactured to ASTM A240 standards, ensuring uniform chemical composition and mechanical properties across 1250mm and 1500mm width plates.
Applications of 348 / 348H Stainless Steel Plate
348 and 348H stainless steel plates are widely used in industries requiring high-temperature and corrosion resistance:
- Power Generation: Boiler tubes, heat exchangers, and turbine components in fossil fuel and nuclear power plants.
- Chemical Processing: Reactors, pressure vessels, and piping handling corrosive media at elevated temperatures.
- Aerospace: Jet engine components and exhaust systems exposed to high heat.
- Oil & Gas: Downhole equipment and refinery components operating in high-temperature, corrosive environments.
- Food Processing: High-temperature sterilization equipment (due to corrosion resistance and ease of cleaning).
