Carburizing is a common case hardening heat treatment for chain processing, chain links are kept in a high carbon environment, and highly reactive carbon atoms spread to the inside steel to form a certain thickness of high carbon content, under the quenching/tempered, the chain link surface will have high content carbon, the inside parts keep the original carbon content, it will get a carbon concentration gradient, this treatment helps chain links to improve the surface hardness and wear resistance, inside keeps toughness. Carburizing treatment has several advantages: increases the work-life, saves the precious steel, and improves the product's performance.

This treatment has 3 steps:


1. Decomposition, highly active carbon atoms decompose from the media.


2. Adsorption, carbon atoms absorbed by the austenite surface, the steel surface carbon content increases.


3. Diffusion, the surface carbon content is higher than inside to form a gradient difference, the surface carbon atoms spread to the inside. But the spread speed mainly depends on the temperature, also about the concentration difference, and alloy steel element content.


Carburizing is a very old craft in China, which can be traced back as early as 2000 years ago. Up to now, it still has high practical value, due to its design ideas. Using cheap carbon steel or alloy steel to replace the precious high alloy steel, also can keep the inside steel a strong toughness to bear the impact loading. It is fully compliant with energy saving, consumption reduction, and sustainable development.
