High quality 1.2344 ESR / NX344 ESR Die Steel


NX344 is a special grade which is developed by our Ningshing Special-Steel.

It is high quality level of 1.2344, a kind of hot work tool steel.

At the beginning, we develop this grade for making plastic mold for high-grade of snack box

because of its better performance on thermal resistance and good toughness that could

improve to get a longer lifetime of the mould.

◆ Heat Treatment

Annealing

750 to 800°C (1382 to 1472°F)

Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to

approx. 600°C (1112°F), further cooling in air.

Hardness after annealing: max. 235 HB.

Stress relieving

600 to 650°C (1112 to 1202°F)

Slow cooling in furnace; intended to relieve stresses set up by extensive machining,

or in complex shapes.

After through heating, hold in neutral atmosphere for 1 - 2 hours.


Hardening

1000 to 1040°C (1832 to 1904°F)

Oil, salt bath (500 - 550°C / 932-1022°F), air

Holding time after temperature equalization: 15 to 30 minutes.

Obtainable hardness:

52 - 56 HRC in oil or salt bath,

50 - 54 HRC in air.


Tempering

Slow heating to tempering temperature immediately after hardening / time in furnace

1 hour for each 20 mm of work piece thickness, but at least 2 hours / cooling in air.

It is recommended to temper at least twice.

A third tempering cycle for the purpose of stress relieving may be advantageous.

1st tempering approx. 30°C (86°F) above maximum secondary hardness.

2nd tempering to desired working hardness.

The tempering chart shows average tempered hardness values.

3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest

tempering temperature.
