Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. But, the working temperature range of DSS is normally narrow as at around 300 o C undesirable intermetallic phases ( -alpha prime phase) start to precipitate which decreases the mechanical properties and corrosion resistance by embrittlement phenomenon. Stainless steel is an alloy of iron that is resistant to rusting and corrosion.It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Above all, because of its chromium content, it is extremely resistant to corrosion. Stainless steel 316 is the second most widely used stainless steel grade next to 304.

Duplex stainless steels (Table 5) have an annealed structure which is typically about equal parts of austenite and ferrite. This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened).Its primary crystalline structure is austenite (face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes them essentially non-magnetic. Stainless steel has high tensile strength, which makes it ideal for use in home construction equipment such as door frames, sinks and other structures.
