When ever heat is applied there occur a change in grain structure.The best working temperature for steel is between 400 - 750 c. If steel is heated below 400c and then cooled it results a brittle zone. And above 750c heavy oxidation losses occur. If rate of cooling is fast it will result in fine grain structure and material will become hard. If rate of cooling is slow coarse grain structure is formed and material will be ductile.

Can spring steel be heat treated?

Definately spring steel can be heat treated and it has to be heat treated before it can be functioned as a spring. The common way to heat treat spring steel is by quenching and tempering.


Is steel iron?

Steel, an alloy, is mostly iron, so it is defined by the amount of other elements in it. Steel contains around 1% carbon. Other alloys, like stainless steel as an example, have 11% and even a bit more of chromium. There are literally dozens of steels, and dozens of ways to treat a given steel to obtain different properties.


How to heat treat 440c stainless?

Heat treating of tool steel is a fairly simple process. Precautions must be taken to protect the tool steel from exposure to oxygen. Tool steels are susceptible to decarburization due to their relatively high heat treating temperature. Stress relieving of the tool steel may be necessary, especially if the tools are complex in design or have been heavily machined. Preheating may be required to reduce the chance of cracking or distortion. The tool steel is generally heat treated between 1500 and 2200F, depending on the grade of tool steel. The tool steel is held at the austenizing temperature longer enough for the elements to be dissolved into solution, then the tool steel is quenched. Quenching can be performed in air, water, oil or vacuum. The quenching medium is determined by the required quench rate and alloy content of the chosen grade. After quenching, the tool steel must be tempered. Tempering is usually perfromed between 350 and 1200F.

What are the effects of tempering of steel?

Tempering Steel is the second stage or process performed on some steels it may have to go through, while it is being heat treated. Once some metals have been heated then quenched or AKA cooled quickly in air , oil or water it becomes hardened very hard this process is know as the Hardening process but also makes steel very brittle like glass to give that steel part its toughness back again the heat treat shop then tempers it after its been hardened this is known as the Tempering Process and takes out some of the hardness, but puts back some of the steel parts toughness so it becomes tougher and more resistant from cracking or braking into piece's when used. This is also known as Tempered Steel.Read more: What_is_tampered_carbon_steel

Why do you heat treat?

You heat treat to improve the molecular structure of the steel. In the untreated state steel is very soft and is relatively easy to bend but when hardened the steel become very hard and brittle. The steel is so brittle after hardening that if say dropped on a concrete floor it may shatter. Tempering relieves some of this stress and makes the steel hard but not too hard.

How hard is stainless steel?

The hardness of stainless steel varies with the alloy and the finish treatment(s). There are hundreds of different stainless steels, and they come in a range of hardness. In addition, there are many ways to treat steel (stainless or otherwise) to increase (or even decrease) its hardness.
