He treating occurs through regulated process that alters the microstructure of metals and alloys such as aluminum and steel. The process is carried out in order to add properties in improve the operational life part. Some of the benefits accrued from this process carried out by heat treating companies include increased temperature resistance, strength, hardness, and ductility. Annealing, case hardening, tempering, normalizing, and solution and age treatment are types of heating services.
Some heat treating services used for various applications include:
Hardening and Tempering
An extensive range of the treating techniques are provided by heat treating companies to enhance hardness, strength, and fatigue life of metal parts.
Anealing Heat Treating
Two stages are preeminent in the process of annealing stainless steel. The first one involves making the metal softer by removing crystal defects that introduce internal stresses in the metal. The second concerns the increase in nucleation of grains which restrain free, a process performed under specific conditions.
Carburizing
As a type of case hardening, carburizing consists of the heating of the metal component that has minimal carbon content in a high carbon gas atmosphere. The process allows for the diffusion of the carbon atoms into the surface parts that need the case hardening application.
Austempering
The objective of austempering services is to create a bainite structure. This is carried out through an isothermal transformation of the ferrous alloy at a temperature below that of pearlite formation but greater than that of martensite formation. The benefits derived from bainite structure formed through this process include:
- Increased strength, toughness, and ductility at a given level of hardness
- Reduced distortion, and subsequently decreased machining time, inspection, sorting, stock removal, and scrap
Normalizing
The process of normalizing, which involves high temperature heating that is carried out prior to cooling in agitated or still air, is carried out for various reasons with one of the main reasons being the homogenization of the metal’s microstructure and the removal of microscopic level non-uniformities.
Carbonitriding
As a modified form of gas carburizing, Carbonite charting creates a thin, high hardness case. It produces increased surface hardness and wear resistance of metal parts.
Experience heat treating companies can provide you with these and other services to help fill requirements of your applications.
