Austenitic and Ferritic Stainless Steels in Practical Applications: Part One

Saturday, January 19th, 2008

The commonest austenitic steel is so-called 18/8 containing around 18% Cr and 8% Ni. It has the lowest nickel content concomitant with a fully austenitic structure. Austenitic steels are prone to stress corrosion cracking, particularly in the presence of chloride ions where a few ppm can sometimes prove disastrous. This is ...

Austenitic and Ferritic Stainless Steels in Practical Applications: Part Two

Saturday, January 19th, 2008

The ferritic stainless steels are somewhat stronger than austenitic stainless steels, the yield stresses being in the range 300-400 MPa, but they work harden less so the tensile strengths are similar, being between 500 and 600 MPa. Ferritic stainless steels, in general, are not as readily deep drawn as austenitic ...

Duplex Stainless Steels: Part One

Friday, January 18th, 2008

Stainless steel is the name given to a family of corrosion and heat resistant steels containing a minimum of 10.5% chromium. Just as there is a range of structural and engineering carbon steels meeting different requirements of strength, weldability and toughness, so there is a wide range of stainless steels ...

Duplex Stainless Steels: Part Two

Friday, January 18th, 2008

Duplex stainless steels (DSS) are widely used in chemical, petrochemical, cellulose and nuclear plants around the world. Because of their fine austenitic-ferritic microstructure they offer an excellent combination of mechanical and corrosion resistance properties. Duplex stainless steels (DSS) are widely used in chemical, petrochemical, cellulose and nuclear plants around the world. ...

Production of Stainless Steel: Part One

Wednesday, January 16th, 2008

In the history of research and development of stainless steels, most important has been the decarburization of high chromium molten steel. Efficient decarburization and the prevention of chromium oxidation losses have been central to the development of steelmaking technology for stainless steels. Because the strong affinity of chromium for carbon, all ...

Classification of Stainless Steels

Saturday, January 12th, 2008

Stainless steels are commonly divided into five groups: martensitic stainless steels, ferritic stainless steels, austenitic stainless steels, duplex (ferritic-austenitic) stainless steels, and precipitation-hardening stainless steels. Stainless steels are available in the form of plate, sheet, strip, foil, bar, wire, semi-finished products, pipes, tubes, and tubing. Stainless steels are iron-based alloys containing ...

Washdown Motors feature stainless steel components

Monday, November 19th, 2007

Available from 1/2-2 hp, Super-E[R] Motors are impervious to rust and deterioration caused by frequent high-pressure caustic sanitizing in food processing and pharmaceutical plants. Encapsulated windings and conduit box lead entry hole, utilizing E3 Effusion Epoxy Encapsulation(TM) process, stop moisture from reaching windings. Hydrophobic aspiration system prevents condensation moisture ...
