Ferritic stainless steels are magnetic, non-heat-treatable steels that contain 1130% chromium but with little or no nickel. They are typically employed for non-structural applications where there is a requirement for good general corrosion resistance or good stress corrosion resistance (an unfortunate synergy of stress and corrosion leading to accelerated failure), such as in sea water applications, and Ferritic Stainless Steel - an overview ScienceDirect TopicsManual metal arc and TIG welding are most commonly used for ferritic grades of stainless steel. Ferritic stainless steels are also sensitive to intercrystalline corrosive attack in the region around a weld that is heated to above 1 100°C. The problem may be avoided by post-weld heat treatment at between 700 and 850°C.

Stainless steels are high-alloy steels which have high corrosion resistance than other steels owing to the presence of large amounts of chromium in the range of 4 to 30%. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure.
Introduction. Stainless steels are high-alloy steels. They have high corrosion resistance when compared to other steels due to the presence of large amounts of chromium. Based on their crystalline structure, they are classified into ferritic, austenitic, and martensitic steels. Precipitation-hardened steels are another group of stainless steels. Stainless Steel - an overview ScienceDirect TopicsStainless Steel. Stainless steels are a family of ferrous alloys containing less than 1.2% carbon and over 10.5% chromium and are protected by a passive surface layer of chromium and iron oxides and hydroxides that protects them efficiently from corrosion.

Categories of stainless steel. Stainless steels are classified into four main categories according to their crystal structure:ferritic, austenitic, martensitic and duplex. Ferritic. Ferritic stainless steels possess a body-centred cubic crystal structure, similar to that of pure iron. The Stainless Steel Family - An OverviewOct 04, 2013 · Ferritic stainless steel. In ferritic stainless steel, the iron and chromium atoms are arranged in what is termed a body-centred cubic structure in which the atoms are arranged on the corners of the cube and one in the centre (Figure 1). As well as being ferro-magnetic, ferritic stainless steel exhibits very high stress corrosion cracking
Ferritic Stainless Steel. Automotive applications use the most ferritic stainless steel. The two most common grades used in this application are 409 and 439. Ferritic stainless usually comes in thicknesses of ¼ in. or less, so most welding with this material is done in a single pass. steel research international - Wiley Online LibraryThe micro-texture of a cold rolled and annealed ferritic stainless steel is characterized and its effects on the surface ridging during tensile deformation is successfully simulated using a developed crystal plasticity finite element model.
