Applications for 13CrMo4-5

The steel is widely used in the power and chemical industries. It is mainly used for the manufacture of various types of

  • pressure vessels
  • steam boilers
  • turbine blades
  • compressed air tanks
  • piping systems

As a material, 1.7335 is especially suitable for fittings which need to be able to transport steam or liquid at high temperatures. Such fittings can be, superheater pipes or steam and outlet ducts.


Properties of 1.7335

The properties of this steel make it particularly suitable for manufacture of, steam boilers, piping systems and compressor tanks. 1.7335 is a material with

  • relatively low carbon content
  • good machining properties
  • excellent weldability
  • retains high strength even at higher temperatures
  • good cold and hot forming properties

The structure of the 13CrMo4-5 material enables the steel to resist deformation and hardening that can occur during mechanical processing. This property means that soft annealing or similar heat treatment is not required prior to machining.
