Rectangle bar 1.4923 is a tempered stainless, high-temperature chromium steel with molybdenum addition, which is used as a standard steel for components in steam turbines and high-temperature bolts. The vanadium addition increases the creep and creep rupture strength. Scale resistance up to approx. 600°C is given.

Overview of the most important steel of 1.4923 steel:

23H12MNF

Applications of 1.4923 stainless steel:

The material 1.4923 is mainly used in turbine construction, aerospace, reactor technology and for pressure and steam boilers.

Characteristics of 1.4923 steel:

Forgeability	good
Weldability	good
Mechanical properties	good
Corrosion resistance	medium
Machinability	medium

Forging:
Forging takes place between 1180°C and 950°C, after the material has been slowly heated to 1150°C – 1180°C. This is followed by slow cooling in dry ashes, furnace or similar materials. After that, heat treatment can be carried out.

Welding:
Material 1.4923 can only be welded under certain precautions. A preheating temperature of 400°C – 450°C and an interpass temperature of 400°C – 500°C is optimal. After welding, the material can be directly quenched and tempered or soft annealed.

If a tempering treatment of the material 1.4923 is to be carried out, the welded joint must be cooled to 100°C -150°C. A tempering annealing of at least 4 hours is performed after complete martensite transformation at 740°C – 780°C. After this, slow cooling must be carried out.

Corrosion resistance:
This is limited due to the relatively low chromium content in natural environmental media. However, corrosion resistance is satisfactory in the absence of salt and chlorine concentrations. The material 1.4923 is resistant to water vapor.

Machining:
This depends on the strength and hardness. For the material 1.4923, the following cutting condition with coated carbide cutting tools can be suggested depending on different microstructural formations:

	Depth of cut (mm)	6	3	1
	Feed rate (mm/U)	0,5	0,4	0,2
Annealed, R_m 700-800 N/mm²	Cutting speed (m/min)	100	130	165

Heat treatment:
Optimum mechanical properties are achieved by quenching and tempering the material 1.4923. The tempering temperature in the temperature range 640°C – 740°C and the subsequent cooling in air depend on the desired strength.

Processing:

Cold forming	only possible to a limited extent
Chip forming	processing is possible
Cold upsetting	only possible to a limited extent
Open die and closed die	forging is possible
