In flame hardening, only a portion of the metal is heated quickly before quenching. This produces a thin, hardened surface, and at the same time, the internal parts remain their original properties along with composition. Capability of hardening of steel much depends upon the percentage of …
Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 ...
induction or flame hardening and must be avoided (e.g. parts made from cold-drawn bright bar which has not been machined on the diameter). • There is a danger of overheating thin sections and edges (e.g. keyways, oil holes, section changes, etc). Where possible, account should be taken of this factor

Introduction to Flame-Hardening: It is a surface-hardening process in which a thin surface section of a component of hardenable steel is heated rapidly by direct application of high temperature flame to a temperature above its upper critical temperature (i.e., it is austenitized), and then the component is quickly quenched in water or oil, transforming austenite to martensite, while the ...
Quench Hardening – Rapidly remove two specimens and quench them in water at room temperature. 4. Tempering – Reheat one of the water quenched specimens to 400oC in another furnace for 30 minutes, then remove it and allow it to cool in air to room temperature. 5.

Flame Hardening Flame hardening is the method of surface hardening most commonly to gray iron After flame hardening, a gray iron casting consists of a hard, wear-resistant outer layer of martensite and a core of softer gray iron, which during treatment ...
Flame and induction hardening are employed to achieve this by altering the structure at the surface by local hardening. While normalized plain carbon steels are used for a number of applications, steels in the hardened and tempered conditions are used when high core strength and good impact ...

Flame Hardening: a gas flame composed of a single (for localised heating) or multiple flame heads (for large surfaces) moves across the surface of the part, raising the temperature up to 850°C, followed by a water quenching head that sprays water at the surface previously heated.Choice of fuels, e.g. acetylene, propane or natural gas. The flame head can be static and the part moves at a ...
Flame hardening is a process where a localized surface of steel is heated using an open flame. It is a surface hardening application that is simple, easily automated and inexpensive.
