Let’s Get Clear on the EN 10204 Standard – PART 1
The EN 10204 standard specifies the different types of inspection documents provided to the purchaser (in accordance with the requirements of the order) for the delivery of all metallic products. For example: plates, sheets, bars, forgings, castings. Regardless of their method of production. These document may also apply to non-metallic products. EN 10204 standard: the […]
Coastal Areas. Which Stainless Steel to Choose in Construction?
Which Stainless Steel to Choose in Construction? In coastal areas the choice of materials to be used in the construction of buildings and architecture is critical. In fact, this choice could impact the safety, durability and aesthetics of the works themselves. As in this case, in very “aggressive” areas such as marine climates. Choose the […]
The Stainless Steel Passivation: Discover the Benefits
In the last lesson we found that stainless steel is more resistant to external agents thanks to Chrome. This is because the latter is an element capable of passivating and protecting steel from corrosion. But what are corrosion and passivation? Corrosion It is the main enemy of all metals. Common steels react with the environment […]
Gutters for a House Near the Sea. Which Material to Use?
Do you have to redo the gutters in a house near the sea? And do you want to know what is the most suitable material in this type of environment? Let’s see together our expert Alessandro’s answer to one of our blog readers who asked us this question. The question Our reader asks if AISI […]
Stainless Steel Decking Screws: 10 Good Reasons to Buy Them!
Are your customers outdoor wood floor installers, on which it’s essential to be able to safely walk on barefoot? Do others ruin the screws breaking the heads while screwing them on the planks? The new stainless steel decking screws are the solution to your problems! Outdoor wood floor (decking screws): small details making the difference […]
Molybdenum – How It Is Being Used
In 1781 the Swedish chemist Peter Jacob Hjelm was able to isolate the molybdenum from its oxide. In fact, this element in nature is present in “molybdenite” usually in the form of sulfide MoS₂ (similar to graphite and lead sulphide). What is molybdenum? Molybdenum is defined a transition metal. What are its characteristics? Here is […]
How to Use Duplex Stainless Steel?
Today we talk about duplex stainless steels. The latter are ferrous steels with a mixed crystalline grain structure of austenite and ferrite. How would you classify these steels? And what are their distinctive characteristics? What are two-phase steels? As mentioned earlier, the microstructure of duplex stainless steels (or two-phase) is called “hybrid”. This precisely because […]
Stainless Steel. How to Prevent General Corrosion?
In regards to metallic materials, we often speak of corrosion. Today, we will focus on its mechanisms, its characteristics and the prevention methods we can implement. What is general corrosion? We speak about general corrosion (or uniform corrosion) when all surfarces of a metal (or a large area) are exposed to an aggressive environment. By […]
How Molybdenum, Nitrogen and Nickel Affects Steel Properties?
After speaking about aluminum, manganese, chromium and copper, in today post we will further focus our attention on three other alloying elements (molybdenum, nitrogen and nickel). And, most importantly, how each of them influences steel properties. Molybdenum: a transition metal Molybdenum (symbol Mo) is considered a transition metal thanks to its atomic number 42 on […]
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 […]
