Corrosion Resistance
• 4724 is resistant to oxidising sulphur bearing gases and displays somewhat less, but still good, resistance to sulphur bearing gasses in reducing environments.
• 4724 displays poor resistance to carburising gasses, and is also not resistant to high temperature nitriding, oxygen denuded gasses. This grade of steel is
resistant to scaling in air up to temperatures of 850 °C.
Heat Treatment
• Optimal material properties are released after annealing by holding in the temperature range 800 °C – 860 °C*, followed by rapid cooling in air or water.

The grade is characterized by:

  • Good resistance to reducing sulphurous gases
  • Good resistance to oxidation in air

This steel can be used at temperatures up to 850°C (1560°F). However, allowance should be made for the low creep strength at the highest temperatures to avoid distortion due to the inherent mass of the steel.
