1.2714 55NiCrMoV7 L6 Steel Material Round Bar Sheet Plate

DIN 1.2714 mold steel was made at the base of DIN 1.2344 mould steel. So it has the advantages of 2344 steel and has better properties. L6 steel has good toughness and malleability. And it also is added the chromium to improve the toughness and fatigue resistance of the 2714 steel material. The Cr content of it is quite high, so it has great hardenability. And air cooling in the time of quenching will get the martensite structure. But its carbon content is on the medium level to make sure to get good hardness after the quenching and tempering. Meanwhile, 1.2714 steel will get good thermostability and high impact toughness. It will get secondary hardening in the high-temperature tempering, then its wearing resistance, corrosion resistance and thermal fatigue resistance will get improve.

So 2714 steel material has good properties after quenching and tempering. But if the surface of steel gets a carbon-denuded layer, it will damage the thermal fatigue resistance.

AISI L6 Steel Heat Treatment

Forging
L6 tool steels are forged at temperatures between 1079°C (1975°F) and 871°C (1600°F).

Hardening
Preheating: Heat L6 steel to 621-677°C (1150-1250°F) and equilibrate. Soak for 30 minutes for the first inch of thickness and 15 minutes for each additional inch.

Tempering
Temper immediately after quenching, and when tempering at 204°C (400°F), hold at that temperature for a minimum of 4 hours, then air cool to ambient temperature.

To minimize the possibility of cracking, steel should be tempered immediately after hardening and should be heated slowly to the required tempering temperature.

Annealing
L6 tool steels are annealed at 788°C (1450°F) followed by slow cooling at a rate of up to 4°C (40°F) per hour.
