PM-12 India: Developments in Powder Metallurgy Components

The benefits of induction hardening, however, come with their own challenges. The porosity present in sintered steels results in decreased thermal conductivity, leading to reduced soaking action from high to low temperature, higher temperature gradients resulting in higher thermal stresses during heating, and slower cooling during quenching.

Porosity increases electrical resistivity leading to larger heat penetration depth and decreased magnetic permeability, resulting in a greater penetration depth and lower electrical efficiency. Even the hardenability and structural homogeneity are affected in the presence of porosity.

how to seal fittings of oil cooler? (urgent answer needed ...

The only thing on a cooling system that must be the product would NPT in the fountain if you use this type. A high temperature sealant paste seems to work best. A connections do not use sealant to seal all that occurs in the conical shape and not at the threads. The connectors have Mocal seals on them (provided you have purchased those recommended by Mocal) and do not need anything extra. That is my hobby BTW.
