ABSTRACT
This chapter focuses on the microstructure and the hardness of water based pack carburized steel towards the dispersion of carbon from the surface toward the core. The metallurgists come up with heat treatment techniques that apply to steel in order to control the issues, a technique which increases the durability and prolongs the product life of the steel since the raw material of the steels is a non-renewable resource and keep depleting. Parts of sustaining the environment are by preserving the nature of the resource. The action can be done by using the source properly and increase the product's potential so it can last longer. Steel making process is familiar with environmental issues but yet, the production demands keep rising as for the development of the industry. The cheapest and easiest type is the pack carburizing. It is environmentally friendly compared to fluid carburizing and it is way cheaper and easily operates compared to gas carburizing.
