What is NAK80 steel?
Description: NAK80 is a precipitation or age-hardened mold steel with a uniform through hardness of approximately 40 HRc. It is super clean, Vacuum-Arc Remelted steel with uniform grain structure, uniform hardness, and excellent dimensional stability.
What is pre hardened steel?
NACHI’s “Pre-Harden” is a high performance steel wire rod which is already quenched and tempered. Precise control of time and temperature during heat treatment produce uniform crystal particles in the steel micro-structure to make “Pre- Harden” tougher than normal steel produced by atmosphere heat treatment.
What is NAK55 material?

How hard is tool steel?
Hardness in tool steels is most commonly measured using the Rockwell C test. Hardened cold work tool steels are generally about 58/64 HRC (hardness Rockwell C), depending on the grade. Most are typically about 60/62 HRC, although some are occasionally used up to about 66 HRC.
What is the strongest and hardest metal in the world?
The 4 Strongest and Hardest Metals on Earth
- Tungsten: The Strongest Metal on Earth. Of all the metals, tungsten reigns supreme in terms of tensile strength.
- Chromium: The Hardest Metal on Earth. Chromium is the hardest metal known to man.
- Steel: The Strongest Alloy on Earth.
- Titanium.
What steel can be hardened?
Only steel that is high in carbon can be hardened and tempered. If a metal does not contain the necessary quantity of carbon, then its crystalline structure cannot be broken, and therefore the physical makeup of the steel cannot be altered. Frequently, the term “hardening” is associated with tempered steel.
