DIWA

DIWA’s patented steels allow significant weight savings in the manufacture of pressure vessels and steam boilers for high operating temperatures. These steels have a higher yield strength at high temperature than other grades of high temperature alloyed and unalloyed steel.

• • DIWA gives you a choice of three grades of high temperature strength. All versions offer properties significantly better than those specified for standardized materials for each specific application.
  • DIWA 353 is suitable for temperatures up to 400° C. DIWA 373 can be used up to 500° C, while DIWA 393 can withstand elevated temperatures up to 375° C in combination with elevated pressure.
  • These high-temperature steels feature low alloying levels of manganese, copper, nickel, and molybdenum and achieve their final properties as a result of the heat treatment that completes their production.
  • Like all Dillinger proprietary steels, DIWA has exceptionally good machinability and, above all, excellent weldability.
  • We are always happy to supply DIWA according to your requirements.
  • DIWA ensures the security of its global links.
