Sell Stainless Steel Iron
Stainless Steel Iron is a term used to describe the extraordinary and highly versatile family of engineering materials, which are chosen primarily because of their corrosion and heat resistance. All Stainless Steel Iron contains a minimum of 10.5% chromium. At this level, chromium reacts with oxygen and moisture in the environment to form a protective, attached and coherent oxide layer, which wraps the entire surface. This oxide film (known as the passive layer or boundary) is very thin (2-3 nanometers). [1nanometre = 10-9 m].
We Sell Stainless Steel Iron Stainless Steel Classification The Stainless Steel Iron family tree has several branches, which can be distinguished in various ways; in terms of their application fields, by alloying elements used in their production, or, perhaps the most accurate way, by metallurgical phases present in their microscopic structures: - Ferritic Stainless Steel - Martensitic Stainless Steel - Austenitic Stainless Steel Iron - Stainless Steel Duplex iron, consisting of a mixture of ferrite and austenite
The passive layer on the Stainless Steel Iron shows off a truly extraordinary property; when damaged (eg abrasion), it repairs itself as chromium in steel reacts quickly with oxygen and moisture in the environment to reform the oxide layer.
Increasing the chromium level beyond the minimum of 10.5% provides greater corrosion resistance. Corrosion resistance can be further improved, and various properties are provided, with the addition of 8% or more nickel. Addition of molybdenum further increases corrosion resistance (in particular, resistance to pitting), while nitrogen increases mechanical strength and increases resistance to pitting.
