Material Considerations

  • Most common grades in this industry are 316L (3), 304L (2) —— parentheses indicate the number of affected areas, starting point for quoting and material procurement.
  • Chloride ions and salt are the most common sources of corrosion (pitting, crevice corrosion) (2/3 hits).
  • What about the overheating of hot zones, leading to heat fatigue and oxidation? (310S / Heat-resistant castings if applicable).
  • Thickness range 2–50 mm: Thin plates are typically formed parts (consider bending rebound and deep drawing cracking), thick plates are mostly welded structures (consider heat input and sensitization).
