Mould steel

H13 DIN 1.2344 JIS SKD61 40CrMoV5 Mould Steel

 

Thermal Treatments

Preheat: 1100/1250F (595/675℃), equalize, 1350/1450F (775/790℃), equalize.

Austenize: 1100/1250F (595/675℃), equalize, 1350/1450F (775/790℃), equalize.

Quench: Air, positive pressure vacuum to 150F (65℃), Interrupted oil to 150F(65℃). NOTE: A minimum quench rate of about 25F per minute from 1800F down to about 1200F is recommended to achieve maximum impact toughness.

Temper: 1000/1200F (540/650℃), hold 2 hours at temperature, air cool. Temper twice.

Cryogenic Treating: Refrigeration treatments may improve long term dimensional stability by transforming retained austenite. Refrigeration treatments should generally be performed after the first temper, and must be followed by a temper.

Surface Treatments

Because of its high tempering temperatures (>1000 F), H-13 may be treated by most surface treating processes, including conventional and ion nitriding, titanium nitriding, and other coatings or treatments. Nitrided surface hardness will be about 60/65 HRC.

Annealing

A. Heat to 1600F (820℃), hold 2 hours, slow cool 25F (0℃)/hour maximum) to 1200F (650C), air cool.

OR

B. Heat to 1600F (820℃), hold 2 hours, cool to 1400F (760℃), hold 6 hours, air cool to room temperature.

Typical annealed hardness: 192/235 BHN.

Stress Relieving

Annealed Material: Heat to 1200/1250F(650/675℃), hold two hours, cool in still air.

Hardened Material: Heat to 25F(15℃) below original tempering temperature, hold two hours, cool in still air.

Welding

Use H-11 or other hot work Tool steel filler material.

Annealed Material: Preheat to 800/1000F(430/540℃). Maintain above 700F(370℃) during welding. Reanneal or temper 1400F(760℃) for 6 hours after welding.

Hardened Material: Preheat to 800/1000F (430/540℃) minimum. Maintain above 700F(370℃) during welding. Cool to 150F(65℃) after welding. Temper 25F(15℃) below original tempering temperature. (1000F(540℃) Minimum)
