Corrosion and heat resistance are important requirements for the Petrochemical industry. A casting is heat resistant if it is capable of sustained operation while exposed (intermittently or continuously) to temperatures that will result in metal temperatures of 650oC and higher. The following are important to know:

  • Corrosion and scaling resistance at high temperatures
  • Dimensional stability i.e. resistance to warping, cracking and thermal fatigue
  • Resistance to plastic flow i.e. creep strength
