Características
1. Cold work tool steel with high dimensional stability at heat treatment.
2. Very high cracking resistance. High machinability, medium thoughness and wear resistance.

Tratamiento térmico
Recocido
680 to 720°C
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air. Hardness af ter annealing: Max. 220 HB.

Endurecimiento
790 to 820°C
Oil, salt bath (200 to 250°C) up to 20 mm thickness. Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 63 – 65 HRC

Alivio de tensiones
Aprox. 650°C
Enfriamiento lento en horno; destinado a aliviar las tensiones generadas por trabajos extensos de mecanizado o en piezas de formas complejas. Tras el calentamiento completo, mantener en atmósfera neutra durante 1 a 2 horas.

Revenido
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.For certain cases we recommend to reduce tempering temperature and increase holdingtime.
