NEUTRAL TREATMENTS

Flame surface hardening

Sometimes only the surface of the part, sometimes the entire part, is heated and hardened.

Induction surface hardening

The surface is hardened by rapidly heating the material to high temperatures and cooling it.

martemperleme-isil-islemi.jpg

Martempering

It is one of the interrupt quench methods. The parts are quenched in a warm bath.

Quench and Temper

The oldest heat treatment method, the material is heated and cooled in a protective or normal atmosphere.

Solution anneal

It is the heat treatment performed before aging on metals hardened by precipitation.

kriyojenik-isil-silem.jpg

Cryogenic

Deep cooling performed to complete the transformation of metals whose martensite finish temp. is at minus tem.

krank-normalizasyon.jpg

Normalizing

It is done to recover the internal structure of the material after processes such as forging, rolling or casting.

vakum-sertlestirme-kalip.jpg

Vacuum

The parts heated in an oxygen-free environment are hardened by pressurized gas. 

gerilim-giderme.jpg

Stress Relief

Heat treatment performed to reduce stresses within the material after welding, plating, grinding or machining.

lazer sertlestirme.jpg

Laser surface hardening

Hardening is done by heating and cooling some of the parts with laser beams.

inis-takimi-ostemperleme.jpg

Austempering

In this process, where thermal shock is minimized, very little stress remains in the part after the heat treatment.

Aging

Hardness gain is achieved by the precipitation of dissolved solid compounds in the matrix.
