In fact, for the production of drinking water and the removal of salt (and other impurities) are necessary: What is the desalination process? Desalination is a process that removes minerals from saline water. More generally, desalination refers to the removal of salts and minerals from […]
Stainless Steel Corrosion Resistance in Seawater
How does stainless steel behave in seawater? This post deals with current and possible uses of high-alloy stainless steels in various marine environments for different applications. Localised corrosion in seawater Stainless steels such as 316L or 304 possess a poor corrosion resistance in seawater. Indeed, if exposed to seawater they may suffer from localised corrosion like pitting, often […]

It’s Chestnut Time! Stainless Steel in Chestnut Processing Plants.
Chestnut processing plants. Autumn has arrived and brings a wonderful fruit: chestnuts. In the latter’s processing stainless steel is indispensable. How? In short: the chestnuts processing After storage in stock, the chestnuts are subjected to a dry cleaning by the sieves. Subsequently, they are naturally sterilized and subjected to curatura soaking process. As a first […]
What Is the Point of Doing the Salt Spray Test?
In the previous post, we explained that it is not possible to determine exactly how many hours a specific type of stainless steel can resist during a salt spray test. But why is this type of test performed? Purpose of the Salt Spray Test The limits of the test are clearly defined by the ASTM […]
Salt Spray Test. How To Interpret the Results.
The salt spray test (or salt frog spry test) is the most popular global test to be performed on stainless steels. And some clarifications are needed. Salt spray test. Some clarifications One of the main things to take in consideration is that of the ASTM B117 “Standard Practice for Operating Salt Spray (Fog) Apparatus” specification. In […]
It’s Grape Harvest Time! Stainless Steel Wine-Making Systems.
It’s grape harvest time in Italy! Stainless steel is a basic material for wine-making systems and breweries. Wine-making systems. Stainless steel is the star! For the design and construction of tanks and wine storage facilities it is usually chosen AISI 304 stainless steel austenitic, as this type of steel is specific for food use (even better […]
Stainless Steel Threaded Fittings. Which Kind of Thread?
Stainless steel is used also as a material for the fittings production, in particular threaded fittings. For example, stainless steel is optimal for the construction and assembly of low-pressure pipes. The threaded fittings in stainless steel AISI 304 and 316 can be derived from: Threaded fittings derived from pipes The threaded fittings derived from pipe are mainly characterized by […]
Small Slotted or Cross Recessed Screws. What Changes From DIN to ISO?
The development of standards is evolving constantly. Their content in fact is constantly changing. And the more important thing is that these changes run with the transition from standard DIN to ISO. As in this case (small slotted and cross recessed screws) Introduction of the ISO standard. What changes? With the introduction of the ISO standards […]
Holes for Screws. What Is the Difference Between Counterbore and Countersunk?
Screw holes? How to create and what tools do you use? Today we will discuss this topic: counterbore and countersunk. Counterbore and countersunk. What are the differences?
