Grade Ferritic Stainless Steels. Description Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface, chiefly caused by the presence of chromium. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to about 20%. Beyond…

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.…

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…

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…

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)…

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…
