In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable", is defined as a steel alloy with a minimum of 10.5% to 11% chromium content by mass. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required. A stainless steel material suffers a generalized corrosion after his immersion in sea water during 30 days. The environment is a closed considered space and do not consider the biological effects on the metallic material surface. The liquid influence on the metallic element surface was analzyed through scanning electrons microscopy (SEM) with 2D and 3D considerations and by energy dispersive X-ray analyze (EDAX) for chemical insights. The nature of chemical compounds appeared on the surface was also established and considered for further corrosion effects investigations. [ABSTRACT FROM AUTHOR] |
