JIS SKH59 Steel Round Bar Sheet Plate Heat Treatment And Produced

1 - Machinability It can be drilled, turned, threaded, broached, milled and tapped when it is in its annealed condition and rated at 45% of 1% carbon steel.

2 - Forging It is preheated to 871°C (1599°F) in a slow manner and then soaked.

This is followed by rapid heating to 1093°C (1999°F) and slow cooling.

It is not suitable that temperatures below 982°C (1799°F) for the forging process.

3 - Tempering M42 tool steel is tempered for three times at 538-593°C (1000-1099°F) and then cooled completely between cycles to get good results.

Tempering is performed in vacuum furnaces or in salt baths.

4 - Annealing Annealing must be performed after hot working and before re-hardening.

Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1500-1575°F (843-857°C), and hold for 1 hour per inch (25.4 mm) of thickness, minimum of 2 hours.

Then cool slowly with the furnace at a rate not exceeding 50°F per hour (28°C per hour) to 1000°F (538°C).

Continue cooling to ambient temperature in the furnace or in air.

The resultant hardness should be 269 HBW or lower.

5 - Hardening It is preheated to 871°C (1599°F), soaked and finally heated to 1204°C (2199°F).

6 - Quenching A salt media is used for quenching M42 tool steel at 538°C (1000°F) and then the steel is air cooled.
