Specificații

In steel H13, the molybdenum and vanadium act as strengthening agents. The chromium content assists die steel H-13 to resist softening when used at high temperatures. H-13 die steels offers an excellent combination of shock and abrasion resistance, and possesses good red hardness. It is capable of withstanding rapid cooling and resists premature heat checking. Tool Steel H13 has good machinability, good weldability, good ductility, and can be formed by conventional means.

Due to H13 tool steel excellent combination of high toughness and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications.


Aplicații:

Oțelul 1.2344 are proprietăți mecanice bune și este utilizat pe scară largă în industrie, cum ar fi formarea matrițelor de extrudare, matrița de forjare cu sarcină mare de impact, matrița de forjare de precizie etc. Poate satisface cerințele de calitate ale matriței. Apropo, suprafața matriței trece prin nitrurare sau cianurare, durata de viață a matriței ar crește.

Specificații:

Preîncălziți înainte de întărire

Se încălzește ușor înainte de încărcare în cuptorul de preîncălzire, care ar trebui să funcționeze la 1400°-1500°F.


călire

H13 tool steel is a steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.


Stingerea

Quench in still air or dry air blast. If complicated forms are to be hardened, an interrupted oil quench can be used. Quench part in oil and remove from the bath when it just loses its color (1000°-1100°F). Finish cooling to below 150°-125°F in air, then tempers immediately.


Calirea

Tempering is carried out in 1.2344 tool steels from 538 to 649°C (1000 to 1200°F) to obtain Rockwell C hardness of 53 to 38. Double tempering can also be performed in these steels for every one hour at the preferred tempering temperature.


AVANTAJ:

High hardenability and toughness

Great resistance for thermal cracking

The secondary hardening ability in tempering is bad due to its lower carbon content

The deformation is small after heat treatment

Bună prelucrare.
