1.2510 steel plate / din 1.2510 die steel / 1.2510 flat steel

1.2510 steel plate / din 1.2510 die steel / 1.2510 flat steel used for high precision and longlife cold work mould,like: punch

General Information:

With chromium-manganese content possessed good machinability, mechanical wear resistance and edge holding quality. Vanadium-Wolfram content reduces high working temperature wear and retention of temper temperature.

Hardening:

-   Temperature: 780-830°C(Slow heating and pre-heat at 350°Cand 650°C).

-   Duration: 30 mins per 25mm thick.

Quenching:

-   Medium: warn oil, salt bath.

Double Tempering

-          Temperature (2 hrs minimum) 250°C, better toughness.(58-59HRC).

-   Temperature (2 hrs minimum) 200°C, higher hardness. (60-61HRC).
