With the development of science and technology, a number of innovative and improved devices and systems have been introduced. From entertainment, health, communication to travel, each and every arena has undergone a change. This rapid growth has also lead to the introduction of induction hardening, an effective and useful heating method.
Induction hardening is generally performed to harden metal parts. However, there are certain factors, which play a great role to make this heating process a successful one. Its essential to take note of the metal's chemistry, the adjustment of the temperature of the metal so that austenitic stage can occur, the characteristics of the metal as well as its capacity to cool down very fast.
Each of the above mentioned factors are essential for this hardening process. If any of these factors is absent, the metal might not harden or soft spots might occur on the metal. These important features or factors have great control over the heating or quenching of the metal.
However, its not only induction hardening procedure that helps in the heating treatment of metals. There are also other kinds of heating methods like annealing, hardening, tempering, carbonitriding, inducting annealing, tempering, homogenizing, case hardening, shot blasting, normalizing, stress relieving etc to materials like cast irons, carbon steels, die steels, alloy steels, tool steels and stainless steels.
Quenching is a very important part in order to get the desired hardness of a metal. Improper quenching may lead to a variety of problems. Usage of a wrong quenchant for a specific metal may cause the process of quenching to become slow. So, it's important to check out whether right and ample amount of quenchant is used for removing the heat or not.
Polymer is mostly used by the water-based quenchants. The use of it basically slows down the cooling process and prevents the occurrence of cracks. However, including too much of polymer isn't a wise idea. This chemical compound may reduce the heat removing ability and cause the metal to remain soft. Also check out whether the item is properly cooled or not or else the residual heat will tamper the metal.
Induction hardening process is used mainly for the steel alloys. This heating treatment mainly aims to improve the wearing behavior, durability and fatigue life of metals and alloys, which are usually used to make springs, gears and shafts.
It's only the professional heat treatment organizations that has the perfect set up and right knowledge to offer. Here are some tips that will help you to find out an expert in heat treatment service.
The hardening service provider must be licensed and authorized to perform the different types of heating treatments. The company you opt must provide quality services. Thus, it's important to learn about the past records of the company in relation to the heating treatment. Find out whether the company uses the right equipments for hardening. Also, take into consideration the company's experience in offering efficient and safe metal hardening services. However, always compare the prices of the different service providers in this industry while finding out the best deal online.
