Heat Treatment Works in Ahmedabad

We are a leading service provider for the Heat Treatment Works in Ahmedabad.



Post Weld Heat Treatment

Post Weld Heat Treatment

Our engineering teams can design solutions in accordance with your unique technical requirements. Post Weld Heat Treatment and preweld heat treatment carried out by coil method with approved procedures and code requirements. We are able to meet all your requirements.





Stress Relieving Works

Stress Relieving Works

We offer Stress Relieving Works for both ferrous and non-ferrous material. This is carried out with the help of latest machines in order to reduce internal residual stresses caused due to various manufacturing processes such as machining, cold rolling and welding.





Gas Carburizing Surfaces

Gas Carburizing Surfaces

Gas Carburizing Surfaces adds carbon to the surface of parts to achieve a very high surface hardness. For most materials, the subsurface becomes a tough & ductile core. Carburized depth (case hardened depth) can be increased with either time or temperature. A quality heat treater will determine the proper processing parameters to achieve the desired properties at minimal cost.





Carbonitriding Process

Carbonitriding Process

We offer Carbonitriding Process, which is mainly preferred in designing tools, dies, crank shafts, gears, bushings, medium sized nuts, bolts, gears and pivots. In this process, we make use of Pit type gas carburizing furnaces to ensure flawless service. Carbonitriding is a process where in both carbon and nitrogen is diffused into the surface thus most suitable for low carbon alloys of steels. Alloys parts are heated in an atmosphere of hydrocarbon which consists of methane or propane and then it is mixed with Ammonia (NH3). This process is a mix of carburizing and nitriding. When it is heated at 900 ºC, 1652ºC it is known as Carburizing whereas Nitriding is carried out at a low temperature of 600 ºC, 1112 ºF. Carbonitriding is done at 760-870 ºC (1400 - 1598 ºF). Then after it quenched in Oxygen free atmosphere which is also known an natural gas, the Quench is little less drastic that simple water or oil thus resulting into very less distortion.

Annealing Process

Annealing Process

Specifications:

  • Annealing Process is a heat process whereby a metal is heated to a specific temperature/color and then allowed to cool slowly. This softens the metal which means it can be cut and shaped more easily. Mild steel, is heated to a red heat and allowed to cool slowly. However, metals such as aluminum will melt if heated for too long
  • Aluminum can be annealed but care must be taken whilst heating. The flame should be held at a distance to the aluminum so that it gives a generalized heating to the metal. A "trick of the trade" is to rub soap on to the surface of the aluminum and then heat it on the brazing hearth. It takes only a short time for the soap to turn black. The brazing torch should be turned off immediately and the aluminum allowed to cool slowly. It is now annealed and should be very soft and malleable





Induction Hardening

Induction Hardening

Induction Hardening is one of EFD Inductions main application areas. Thousands of our hardening solutions are at work around the world's many of them within the automotive industry. The main benefit of induction heating for hardening is that it takes just a few seconds. In a furnace, the same process can take hours or even days. How is that possible? The answer is that induction is phenomenal at generating heat fast. This, in turn, means you can integrate hardening in the production process. Hardening in a furnace, on the other hand, is more time-consuming (greater heat loss) and requires moving the components either to your own furnace or to that of a sub-contractor. In-line integration of hardening reduces your lead times considerably. You get full control over quality, delivery times and costs. There's no need to transport kilos of components back and forward, which saves energy and the environment. And last but not least, you cut down the amount of administration to a minimum.





Electric Muffle Furnace

Electric Muffle Furnace

A muffle furnace is (usually) a front-loading box-type oven or kiln for high-temperature applications such as fusing glass, creating enamel coatings, ceramics and soldering and brazing articles. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is non-combustible and non-volatile (i.e., ash). Some digital controllers allow RS232 interface and Permit the operator to program up to 126[citation needed] segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide offered in certain models by Vecstar, can now produce working temperatures up to 1800 degrees Celsius, which facilitate more sophisticated metallurgical applications.[citation needed]

The term muffle furnace may also be used to describe another oven constructed on many of the same principles as the box type kiln mentioned above, but takes the form of a long, wide, and thin hollow tube used in roll to roll manufacturing processes
