Carburizing - Wikipedia

Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Depending on the amount of time and

Atmosphere Treating | L&L Special Furnace Co., INC.

Gas fired atmosphere box furnaces require the use of radiant tubes which separates the products of combustion from the internal furnace atmosphere. the work needs to be wrapped in stainless steel foil or some carbon monoxide and free carbon needs to be added with either a hydrocarbon gas or carburizing compound.

Gas Carburizing Fundamentals - Worcester Polytechnic Institute

enriching gasses, kinetics of mass transfer at the gas-steel interface and carbon diffusion in steel. The models accurately carburizing, 2) the kinetics of carbon transfer at the gas-steel surfaces, and 3) the carbon diffusion . Gas carburizing in batch furnaces is a widely adapted procedure used for surface hardening, yet.

Industrial furnace for steel hardening, tempering, quenching and

Industrial furnaces for steel hardening, tempering, quenching, annealing, bright carburizing to harden, temper, quench, aneal steel parts or fastenings. In gas carburizing, commercially the most important variant of carburizing, the source of carbon is a carbon-rich furnace atmosphere containing CO, produced either from

Carburizing Process and Techniques - Four Methods of Carburizing

May 25, 2011 Carburizing is basically a case hardening technique that involves the addition of carbon on top of a metal surface layer to improve the metal properties. Gas carburizing is theoretically similar to pack carburizing aside from the supply of carbon monoxide gas to the heated furnace and the carbon

Evaluation and Diffusion Assessment for Surface Hardening

In order to cause carbon to diffuse in to a steel surface, the steel is heated to the austenite region in a carbon containing gas, such as carbon monoxide. The carbon from the carburizing compound soaks in to the surface of the hot steel to depth which depends on the time that the boxes are left in the furnace, so that the low

Key words: Heat treatment, furnaces, atmosphere, annealing, sintering, heating. Selection of atmosphere: The surrounding in the thermal enclosure (furnace) is termed atmosphere. The atmosphere carburization, heat treatment of steel of any carbon content, bright copper brazing, and carrier gas for gas carburizing or

Introduction to Surface Hardening of Steels - ASM International

Low-carbon steels, low-carbon alloy steels. Excellent process control; bright parts; faster than gas carburizing; high equipment costs. Nitriding. Gas/LPN .. very low pressure (vacuum carburizing) has been explored and developed into a viable and important alternative. Although the furnace enclosure in some respects
