This manual does not pretend to introduce stainless steels in depth and in all their aspects, nor to exhaust the subject in this short manual.

We simply attempted to accomplish for the generic user a sort of guide, a good practice manual, so as to provide the essential elements to cope, quickly, to the many questions that often arises in the design phase, machining or installation.

What are Stainless Steels?

Stainless steels are iron alloys that are able to combine the typical mechanical properties of steels, the intrinsic characteristics of noble materials such as typically the remarkable qualities of resistance to corrosion.

Which types of stainless steel exist?

Staiinless steels can be divided into three main groups: martensitic, ferritic and austenitic.

Phisical and machanical properties

Stainless steels have a wide range of both physical and mechanical properties for the most disparate application situations.

Different steel products

The considerable diversification of industrial applications reached by the stainless steels has necessarily brought the processors companies need to be able to have different steel products on the market in various formats.

Resistance to corrosion

It is always very aleatory be able to provide, in general, the behavior in time of a given metallic material if put in contact with a certain environment.

How to work them

Working with stainless steels requires knowledge of some of their special characteristics and needs taking into account the attitudes of the different alloys to machining and structural changes that can occur during the processing stages.


The bonding techniques can be adopted with steels are varied, both in fixed joints and removable joints.

Surface finishings

The considerable diversification of surface finish semi-manufactured or manufactured goods with steel plays a decisive role.
