Heat Treatment

Atashgah Steel Company, utilizing two separate halls for heat treatment, has the ability to perform a variety of heat treatment processes on its produced alloys. These processes are carried out in two main categories: heavy furnaces and semi-heavy and light furnaces, enabling heat treatment on parts ranging from small to large and extra-heavy sizes.

Each alloy requires specific heat treatment processes depending on its chemical structure and industrial application. The following table shows the specific heat treatment processes for each alloy:

Alloy Group	Heat Treatment Process	Description of Operation
Ni-Hard Cast Iron	1. Preheating \| 2. Austenitizing \| 3. Air Quenching \| 4. Tempering	Increase hardness, wear resistance, and toughness
Ductile Cast Iron (Malleable)	1. Annealing \| 2. Normalizing \| 3. Quenching and Tempering	Optimize mechanical properties and increase strength
High Chromium Cast Iron (Hi-Cr)	1. Homogenization \| 2. Austenitizing \| 3. Air Quenching	Increase wear and corrosion resistance
Manganese Steels (Hadfield)	1. High temperature solution treatment \| 2. Rapid water quenching	Increase toughness and impact resistance
High Carbon and Low-Alloy Steels	1. Normalizing \| 2. Surface hardening \| 3. Quenching and Tempering	Increase surface hardness and mechanical strength
Austenitic and Martensitic Wear-Resistant Steels	1. Austenitizing \| 2. Air Quenching \| 3. Tempering	Increase wear resistance and optimize toughness
Tool Steels	1. Preheating \| 2. Austenitizing \| 3. Air Quenching \| 4. Tempering	Increase hardness and fatigue resistance
Stainless Steels	1. Annealing \| 2. Solution hardening \| 3. Tempering or Nitriding	Improve corrosion resistance and mechanical properties

Heavy furnaces: For operations on large and heavy parts such as mill liners, industrial gears, and mining equipment
Semi-heavy and light furnaces: Suitable for operations on smaller parts such as crusher hammers, anti-wear parts, and precision engineering parts
Use of temperature control and data recording systems: All processes are carried out under precise temperature and timing control to ensure optimal mechanical properties.

- Increase the service life of parts by optimizing hardness and strength
- Reduce maintenance costs in mining, steel, cement and copper industries
- Improve resistance to wear, impact and corrosion
- Ability to implement custom cycles according to customer needs
