How much do you know about boiler steel

Boiler steel, also called pressure vessel steel, is designed to manufacturing steam boilers, pressure vessels and other pressure vessel structures. Because this kind of material bears certain air pressure and water pressure, as well as used in environments of different temperature, like high, medium, low temperature, the requirement for this kind of steel is more strict.

Classification:

Per Composition
  • Carbon Steel
  • Alloy Steel
Per Strength
  • High Pressure
  • Medium Pressure
  • Low Pressure
Per Temperature
  • High Temperature
  • Medium Temperature
  • Low Temperature

Heat treatment:

  • Normalizing
  • Annealing
  • Tempering + Normalizing
  • Quenching + tempering

AHL steel is specialized in all kinds of boiler and pressure vessel steel plates for various pressure and temperature requirements.
