This treatment achieves the maximum softening results and its three key factors are: The following are the most common types:.

They can be divided into 2 groups:. In these conditions, both cathode areas inside the grain bodies and anodic areas areas with low percentage of Cr, near the grain boundary are formed.

Their main characteristic is to avoid Cr carbides and therefore a loss in corrosion resistance. These alloys acfiai particular resistant to high temperature. In this particular condition each grain separates from the others and inissidabili can be taken away form any mechanical action. Austenitic Steel Austenitic steels can be divided into 3 groups, depending on the heat treatment:. It has been created in order to obtain better toughness in welded structures.

With quantities around 0. Two treatments are available for alloy Each alloy has a certain fatigue limit, without any stress maximum cyclic stress within a certain time.

Consideration on alloy Bigger grains generally lead to more severe corrosions. The passive film dissolves in reducing solutions chloride acid, sulphur acid, concentrated organic acids, etc and the steel is corroded at a similar speed as normal steel. The smaller the ratio between the anodic and cathode area, the quicker the more anodic material will oxidise. An increase of Ni content means a decrease of hardening within the rolling process.

It has excellent performance against corrosion resistance. In this brief introduction, we will consider only austenitic and ferritic steels, which are produced by Arinox S. It is a spotted corrosion which may reveal if an item shows gaps between the two coupled metallic parts’ surfaces. Inter-crystalline corrosion It is a selective type of corrosion as it attacks the grain boundary. Basically they are high-alloyed steels and more precisely alloys in Iron – Carbon — Chrome: Inter-crystallizing corrosion sensitisation This treatment is used only for laboratory purposes and it has to be avoided in practical applications to establish the sensitivity to inter-crystalline corrosion.

The corrosion attack is anyway less dangerous since the thickness reduction is uniform and can be calculated. For about Stainless Steels: Generally, resistance to corrosion is good within medium-aggressive solutions, providing oxygen or other oxidising solutions presence.

Their characteristics are similar at room temperature but slightly less performing at high temperatures. Passive material can be defined as material that is able to oxidise thermodynamically but the speed of this process is so low that the corrosion effect is almost negligible. It is used when large quantities of product and a good resistance to corrosion are required.

This layer glli mainly made of chrome oxides and metallic oxides, all of the Me OH type. Re-crystallization Treatment temperatures are different from one alloy to another, and for the same alloy they can be different depending on the way of rolling.

AISI It is the most used alloy because of its low cost. This corrosion can either penetrate in depth inosssidabili Figure A or expand in a shape of a cave see Figure B. In case of extremely hard rolled material e.

The main corrosion types are therefore listed below. Corrosion begins on the surface area where it is more difficult to create a condition of vaprio passivity.

The corrosion process has specific characteristics, which differ from those occurring without either static or dynamic stress.
