    THE FIRST STAINLESS STEELS HAVE BEEN DEVELOPED BY THE GERMAN INDUSTRY IN THE EARLY TWENTIETH CENTURY. THE GENERIC TERM “STAINLESS STEEL” INVOLVES MANY TYPES OF STEEL ALLOY WITH HIGH CORROSION RESISTANCE, WHICH EMERGED AS RESPONSE TO INDUSTRY REQUESTS.

    Stainless steel is recyclable and itself results largely from recycled steel scrap.

    One of the great advantages of using stainless steel is that does not require surface treatment by galvanization to give the finish to the final product. In this way all industrial chemical processes, almost pollutant , mainly by galvanic way have been removed. It’s possible to reach high quality finishing’s identical to the “chrome plated” in the case of polished steel or “Mate” finishing’s in the case of satin finish or sand finish or even industrial “Raw” finish. It is also possible to carry out special finishes on stainless steel, using the technology “PVD” (Phisical vapor deposition), obtaining products with a higher surface hardness and different color of the steel as is the case of gold or black color satin or mirror appearance. Typically stainless steel is “recoverable” by mechanical or chemical process. It’s possible to recover the appearance of a new product after many years of use.

    Stainless steel is an alloy that contains, among other elements, chromium, nickel and molybdenum which confer high resistance to corrosion. The corrosion resistance is mainly due to the chromium. To be considered a steel “stainless steel, must contains at least 10.5% chromium. The corrosion resistance is due to a chromium oxide film formed on the steel surface which acts as self-protective. The process of formation of this “film” is also known as passivation.

    The Nickel essentially change the mechanical characteristics of the steel in terms of hardness in order to improve the machining process.

    It is one of the stainless steels most widely used in construction industry. 

    Non-magnetic steel which can be slightly magnetic converted if machined. It has an excellent characteristic of hardness and corrosion resistance. 

    Minimum contents of chromium is 18% and 8% nickel.


    EN 1.4301 ( AISI 304 ) Austenitic

    It is slightly more resistant to corrosion compared with AISI 304. Non-magnetic steel which can be slightly magnetic converted if machined. 

    Recommended for areas of high salinity, for example in coastal areas or in very polluted places , or in contact with agressif chemicals, as acids and bases. 

    Has a minimum content of chromium 18% , niquel 10% and2% molybdenum. 


    EN 1.4372 ( AISI 201 ) Austenitic

    Stainless steel with low nickel contents and is therefore a high hardness steel. Corrosion resistance is acceptable for almost applications, except in coastal areas or heavily polluted. 

    Non-magnetic steel which can be slightly magnetic converted if machined. 

    It has minimum content of 17% chromium, nickel 3.6%, 7% manganese.


    EN 1.4016 ( AISI 430 ) Ferritic

    Stainless steel commonly used in food industry. Typically used in non-aggressive atmospheres. Magnetic steel with an acceptable corrosion resistance. High quality surface finish.
