Hardness :Annealed(+A) max: 197 BHN
L2 tool steel when heat-treatment the preheat Temperature need reach 649°C, and the temperature may be ± 14 °C .
L2 tool steel when austenitizing ,should keep 5-15 minutes long. If is the salt bath ,temperature should keep in the 857°C and shall be ± 5.6 °C. Or is the controlled atmosphere furnaces, temperature should keep in the 871°C, and shall be ± 5.6 °C.
Quenching: L2 tool steel Hardening quenching using oil cooling, and it's hardness min is 53RC.
Tempering: L2 tool steel general tempering temperature is 204°C. Double tempering of Double tempering of L2 tool steel is recommended.
Application:
L2 tool steel are frequently used in cold work applications requiring toughness at relatively high hardness
Ultrasonic Test:Material will be ultrasonically tested at appropriate stages of the manufacture to ensure the quality, as agreed between seller and purchaser.
