Specifications

steel

General Information:                                                                                                                                       

This steel with hardening air, oil and salts bath. It features good resistance and toughness for hot and cold treatments. Normally used for mould carrier frames, containers for pressure casting, sub-dies for extrusion of aluminum, plastic moulds.

Comparable Standards:                                                                                                       

 Chemical Analysis (%):                                                                                                         

Heat treatment                                                                                                       

Isothermal annealing:

-   Heat to 870÷880°C;

-   Furnace cooling to 760°Cand hold at temperature for at least 10 hours;

-   Cool by 10°C/h to 720°C;

-   Cooling in air.

Stress relieving:

To be carried out after machining and before the final heat treatment.

-   Heat to 650÷700°C, hold for 4/6 hours:

-   Furnace cooling to 330÷350°C;

-   Cooling in air.

Hardening:

-   Initial preheating to 350÷450°C;

-   Second preheating to 750÷850°C

-   Austenitizing at 1010÷1040°Cor at 1080÷1100°C;

-   Cooling in air or in oil if large parts.

Quenched hardness: 62÷66 HRC

Tempering:

    In the temperature range 150÷300°Cwith minimum holding time 3 h. For parts hardened at 1080÷1100°C, a first tempering will be carried out at 500÷550°Cin order to exploit secondary hardness, followed by a second tempering at 180/300°C.
