The BenefitsHeat Treatment Process StepsPhase DiagramsCommon Heat Treatment MethodsWhat Metals Are Suitable For Heat Treating?There are various reasons for carrying out heat treating. Some procedures make the metal soft, while others increase hardness. They may also affect the electrical and heat conductivity of these materials. Some heat treatment methods relieve stresses induced in earlier cold working processes. Others develop desirable chemical properties to metals.

Heat Treatment Furnaces Furnaces for Heat Treating Iron and Steel GHI designs and installs a wide variety of furnaces for performing the most common treatments in the iron and steel industry, such as for example steel quenching and heating treatment of rolls, tubes, forged parts, cast parts, screws, nuts and bolts, large parts and diverse parts for the automotive industry.(plate) Heat Treating Ovens Heat Treating Furnaces Aging Ovens(steel) INDUSTRIAL HEAT TREATING OVENS AND FURNACES. Heat treating is the heating and cooling of metals and alloys to achieve a desired physical and mechanical property such as strength, hardness and resistance to fatigue or failure. Heat treating is a precise science that is made more complex by the varying properties of metal alloys.
May 20, 2019The type of hydrogen used in heat treatment furnaces is referred to as dry hydrogen and is 98 99.9% pure. Endothermic Atmospheres The protective gases used in furnace atmospheres are usually a mixture of hydrogen, nitrogen, carbon dioxide (CO2), carbon monoxide (CO), and trace amounts of water.(plate) Heat Treatment Processes Types, Methods, Purposes (steel) What Is Heat Treatment?Types of Heat Treatment ProcessesTypes of Heat TreatmentPurpose of Heat Treatment of Steel1. Annealing
Annealing is one of the most important processes of heat treatment. It is one of the most widely used operations in the heat treatment of iron and steel and is defined as the softening process. Heating of from 30 50°C above the upper critical temperature and cooling it at the very slow r2. Normalizing
Normalizing The main aim of normalizing is toremove the internal stresses developed after the cold working process. In this, steel is heated 30 50°C above its upper critical temperature and cooling it in the air. It improves mechanical and electrical properties, machinability & tensile stre3. Hardening
Hardening The main aim of the hardening process is to makesteel hard tough. In this process, steel is heated 30° 40°C above the upper critical temperature and then followed by continues cooling to room temperature by quenching in water or oil. It is the opposite process of annealing.See more on theengineerspostEstimated Reading Time 6 minsDaido Plant Industrial (steel) Continuous Heat Treatment Furnaces Batch Type Annealing Furnace Electro Zinc Plating Line Zinc Aluminum Compound Coating Lines Inspection Machines Material Supplier Kobe Steel , Daido Steel , Nippon Steel .
