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, …
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 …
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 the answer …
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 …
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 …
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 …
In relation to metallic materials, often speaks of corrosion. Today we talk about the general corrosion. We will focus in particular on its mechanisms, its characteristics and the prevention criteria that we can implement. What …
After speaking about aluminum, manganese, chromium and copper, in today’s post we will further focus our attention on three other alloying elements (molybdenum, nitrogen and nickel). And most importantly, how each influence steel properties. Molybdenum: …
Corrosion resistance. This post deals with current and possible uses of high-alloy stainless steels in various marine environments for different applications. A survey of the general behavior of stainless steels in seawater.
The corrosion resistance of stainless steel can be affected by steel contamination. This is the consequence of operations of cutting, grinding and welding of carbon steel which flow of the particles.
