The typical Austentic Stainless Steel – 18%Cr + …

1 The typical Austentic Stainless Steel 18%Cr + 10% Ni have been adopted in corrosion resistant application for decades. In accordance with more and more application, the typical Austentic Stainless Steel is not capable for mor e severe environment. More and stronger corrosion re sistant ability by manifesting the feature of various element, are demanded by the market. With wider sources of castings and bar material, this year, 2010, Modentic decide to involve more in this field. Besides the casting, Modentic also storage the bar material. Ball valves in sizes below 6 are available in the short delivery from the warehouse.

3 Increasing the level of chromium enhances corrosion resistance. At elevated temperatures, chromium provides resistance to oxidation and sulfur-containing and other corrosive atmospheres; contributes to high temperature creep and rupture strength; and, in some alloys, increases resistance to in Stainless steels promotes the stability of austenite. Austenite is stronger and more stable at higher temperatures then ferrite. Less nickel is needed to retain an austenitic structure as the nitrogen or carbon levels increase. When sufficient nickel is added to a chromium Stainless Steel , the structure changes from ferritic to austenitic.

4 Adding nickel improves toughness, ductility, and increases resistance to oxidation, carburization, nitriding, thermal fatigue, and strong acids, particularly reducing acids. It is an important alloying element in Stainless Steel and nickel-base alloys used for corrosive and high temperature additions improve resistance to pitting and crevice corrosion in chloridecontaining environments and corrosion by sulfuric, phosphoric, and hydrochloric acids.
