🔍 What is Nitriding?

Nitriding is a low-temperature surface hardening process that introduces nitrogen into the outer layer of steel to create a hard, wear-resistant surface without affecting the core structure.

Unlike other heat treatment methods, nitriding does not involve quenching, which greatly reduces distortion and cracking — making it ideal for precision components.

✅ Why Choose Nitriding?

• 🔒 Hard surface for wear and fatigue resistance
  
  

• 🛠️ Low distortion – perfect for tight tolerance parts
  
  

• 🔁 Improves resistance to corrosion, scuffing, and seizure
  
  

• 🔩 Extends component service life without post-machining
  
  

⚙️ How Nitriding Works

The part is heated (typically 500–550°C) in a controlled nitrogen-rich atmosphere — such as ammonia gas — allowing nitrogen to diffuse into the steel surface.

The nitrogen reacts with alloying elements like aluminium, chromium, and molybdenum to form hard nitrides, resulting in a tough outer layer.

🧪 Nitrided hardness can reach HV 600–1200, depending on the material.

🛠️ Applications of Nitriding

Nitriding is commonly used for parts that require surface durability, minimal distortion, and long wear life:

• Gears & shafts
  
  

• Crankshafts & camshafts
  
  

• Dies and moulds
  
  

• Valves & spindles
  
  

• Pistons & sleeves
  
  

• Tooling components
  
  

• Screws and fasteners
  
  

• Aerospace & automotive parts
  
  

🧱 Suitable Materials

Nitriding works best with alloy steels that contain nitride-forming elements, such as:

• 4140 / 4340 / SCM415 / SCM435
  
  

• H13 / SKD61 / SKD11
  
  

• 38CrMoAl
  
  

• Nitralloy steels
  
  

• Stainless steels (select grades)
  
  

Not all steels are suitable — our team can help you verify material compatibility.

📏 Case Depth & Process Control

• Typical nitrided case depth: 0.1 mm – 0.6 mm
  
  

• No phase change or quenching
  
  

• Excellent dimensional stability
  
  

We monitor time, temperature, and gas flow to ensure repeatable and uniform results.
