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

  1. High-Temperature Resistance: Exceptional creep strength and oxidation resistance at temperatures up to 800°C (1472°F), making it ideal for high-heat environments.
  2. 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).
  3. Austenitic Structure: Non-magnetic, with excellent ductility and formability, allowing for easy fabrication (welding, bending, cutting).
  4. 348H Variant: Higher carbon content in 348H improves high-temperature strength, making it preferred for critical pressure vessel and boiler applications.
  5. 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).
