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:
Element348 (ASTM A240)348H (ASTM A240)
Carbon (C)0.08 max0.04 – 0.10
Chromium (Cr)17.0 – 19.017.0 – 19.0
Nickel (Ni)9.0 – 13.09.0 – 13.0
Niobium (Nb)10×C min (0.70 min)10×C min (0.70 min)
Titanium (Ti)0.10 max0.10 max
Manganese (Mn)2.00 max2.00 max
Silicon (Si)0.75 max0.75 max
Phosphorus (P)0.045 max0.045 max
Sulfur (S)0.030 max0.030 max
Nitrogen (N)0.10 max0.10 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:
Property348 (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).
