Stainless Steel Melting Processes
The first materials able to withstand the aggressive action of the acids were discovered in 1821, thanks to the mixing and the merger of oxides of iron and chromium. A little bit of history Initially, this alloy contained a percentage of chromium of around 1.5 and high carbon values. Only at the end of the […]
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 […]
2016 – The Recovery of Nautical Market in Mediterranean Area

How to prepare your boat for winter storage? Remind your customers of some tricks before putting their boat in “hibernation” […]
Stainless Steel – What to Make in Case of Contamination?
The corrosion resistance of stainless steel can be affected by steel contamination, a consequence of carbon steel cutting, grinding and welding operations. Steel contamination. What happens? The presence of contamination on the metal surface creates: The iron particles which are deposited on the surface of stainless steel will oxidize very quickly and form rust. This could also happen […]

Why Is Austenitic Steel Magnetic?
Today we want to deal with a very complex subject: magnetism in austenitic steel. Austenitic steel. Why do they become magnetic? Austenitic steels contains Cr (16 – 20%), Ni (7 – 18%) and only some kinds Mo (2 – 6%) with a carbon content of typically less than 0.08%. The presence of stabilizing elements (such as Ti) improves the corrosion resistance, […]
High And Low Temperatures. When To Use Stainless Steel?
