Heating of Steel: Oxidation and Decarburisation | Metallurgy

When a steel part is heated to high temperatures for heat treatment, its surface reacts chemically with the surrounding medium in the furnace. The furnace atmosphere may consists of various gases depending on the conditions of combustion and the temperature The common furnace gases are O2, CO2, CO, H2, H2O (water vapour), N2, CH4, etc. As a result, two undesirable [...]

Heating of Steels: Furnace Atmospheres and Its Conditions | Metallurgy

In this article we will discuss about the types of furnace atmosphere and process of choosing controlled furnace atmosphere for heating of steel. Types of Furnace Atmospheres for Heating of Steels: 1. Exothermic Atmospheres: This name has been given to these atmospheres because these are produced by the exothermic combustion (i.e. without the addition of heat) of gas, and air, [...]
