What Is Austenitic Stainless Steel?

December 1, 2020

Stainless steel material is a form of steel that contains significant amounts of chromium, nickel, often manganese, molybdenum, and nitrogen as a supplement to the iron base. The addition of nickel is key to otherwise ferritic chrome-iron alloys. This can yield predominately austenitic alloys. The microstructure change brings a marked increase in ductility and toughness.…

Near-Net Shaping: Combining Shaping Technology with the Centrifugal Process

December 1, 2020

What is the Near-Net Shape Manufacturing Process? Near-net shaping combines various shaping technologies, such as sand casting and investment casting, with the high-integrity centrifugal process to maximize the benefits of each. Net-shaping can be readily added to add O.D. profiles to centrifugally cast components through the use of sand, ceramic, or split graphite dies. True…

Material Applications: Alternative Corrosion Resistant Materials

December 1, 2020

Coatings of various types are often used to enhance corrosion resistance in metals when metallic properties like strength or durability are needed for the application. There are, of course, also non-metallic solutions often used to protect against corrosion.  As with most alternative corrosion materials, there are advantages and disadvantages associated with each. Ceramics Ceramics are…

What Is Pitting Resistance Equivalency Number (PREn)?

December 1, 2020

The Pitting Resistance Equivalency Number (PREn) is an objective way to do an initial comparison of the relative resistance to corrosion of various metals. It is based on a calculation that considers the weight percentage of alloying elements. Pren Number Formula: PREn = % Cr + (3.3 x % Mo) + (30 x % N)…

Nickel: Where Does It Come From?

December 1, 2020

Because of its strength, toughness, and resistance to corrosion, nickel is a key component of stainless steels.  In fact, the majority of the world’s nickel is consumed in the creation of stainless steel. Where Does Nickel Come From? Most materials don’t just “appear” but, in a way, some of the nickel on earth has done just…
