304 | 304L | 304H Stainless Steel Plate

The 304 stainless steel series plates are austenitic stainless steel made primarily of chromium and nickel. They are renowned for their excellent corrosion resistance, high strength, and good formability. This makes them ideal for a range of industries, including chemical processing, food processing, and construction.
  • 304 Stainless Steel: Standard grade, suitable for general use with good corrosion resistance and durability.
  • 304L Stainless Steel: Low-carbon version, ideal for welding with minimal carbide precipitation.
  • 304H Stainless Steel: High-carbon variant designed for high-temperature applications with enhanced strength.
Choose 304 for general use, 304L for welding-heavy tasks, and 304H for environments with high temperatures. Each variant is tailored to meet specific needs in industrial settings.

Heat Treatment

Heat Treatment

A 304 stainless steel plate is undergoing heat treatment.

Common heat treatment methods of SS 304/304L/304H plate include:

  1. Normalizing
    • 304, 304L, and 304H stainless steel typically do not undergo normalizing.
  2. Annealing
    • 304: Annealing temperature 1010°C-1120°C, followed by rapid cooling (water quenching).
    • 304L: Annealing temperature 1010°C-1100°C, followed by rapid cooling (water quenching).
    • 304H: Annealing temperature 1050°C-1120°C, followed by rapid cooling (water quenching).
  3. Quenching
    • After annealing, all three require rapid cooling (water quenching) to prevent intergranular corrosion.
    • 304L is less sensitive to intergranular corrosion due to lower carbon content.
    • 304H is more prone to carbide precipitation during heat treatment, so careful cooling rate control is necessary.
  4. Tempering
    • 304 series stainless steel is usually not tempered.
    • 304H may occasionally be tempered after high-temperature applications to stabilize its properties, but this is not a standard procedure.

Characteristics

Characteristics

SS 304 Plate:

  1. Good resistance to corrosion and rust.
  2. Strong and durable for a variety of applications.
  3. Easy to weld and fabricate.
