Stainless steel tube annealing machine which is good for stainless steel bright annealing

When processing steel, everyone knows that there are many processes, and each process has different equipment for processing. The following is a description of the equipment used in the annealing process in stainless steel processing: Which is good for stainless steel tube annealing machine? The following is for everyone to introduce.


Stainless steel tube annealing machine What is an annealing furnace?

An annealing furnace is a process used in the manufacture of semiconductor devices that includes heating a plurality of semiconductor wafers to affect their electrical properties. Heat treatment is designed for different effects. The wafer can be heated to activate the dopant, convert the film into a thin film or convert the film into a wafer substrate interface, make a densely deposited film, change the state of the grown film, repair the implanted damage, move the dopant or dope The agent is transferred from one film to another or from the film into the wafer substrate.

The annealing furnace can be integrated into other furnace processing steps, such as oxidation, or it can be disposed of by itself. The annealing furnace is completed by equipment designed to heat semiconductor wafers. The annealing furnace is an energy-saving periodic working furnace with ultra-energy-saving structure and fiber structure, saving 60% of electricity.

What is the role of stainless steel annealing?


The formation of stainless steel is to add other relevant elements during the iron and steel smelting process, so that the finally obtained alloy has corrosion resistance. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum is less than 1.2%, and the ωc (carbon content) of some steels is even lower than 0.03% (such as 00Cr12). ). The main alloying element in stainless steel is Cr (chromium), and the steel has corrosion resistance only when the Cr content reaches a certain value. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%. The stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.

[The role of stainless steel annealing]

1. Reduce hardness and improve plasticity;

2. Refine the grain and eliminate the missing items;

3. Eliminate internal stress;

4. Prepare the organization for quenching.


Which is better for stainless steel tube annealing machine?


Haituo electromechanical annealing furnace application: Mainly used for vacuum heat treatment of high speed steel, hot and cold work die steel, stainless steel, elastic alloy, high temperature alloy, magnetic material and titanium alloy, vacuum brazing and vacuum sintering.
