8 sie 2024 · Ferritic Stainless Steels Grades. Ferritic stainless steel contains 10.5% to 27% chromium, little or no nickel, and is lower cost. It is magnetic, non-hardenable by heat treatment, and has good corrosion resistance.
15 paź 2023 · Stainless steel is a broader term covering austenitic, ferritic, martensitic, ferritic-austenitic (Duplex) and precipitation hardened stainless steels. Each of its types has unique properties and applications & unique microstructures.
Ferritic stainless steel [2] [3] forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and precipitation hardened. [4] For example, many of AISI 400-series of stainless steels are ferritic steels.
27 gru 2023 · Ferritic Stainless Steel. Ferritic stainless steels possess a ferritic body-centered cubic (BCC) crystalline structure. The main alloying element, chromium, makes up between 10.5% and 30% and carbon never exceeds 0.2%. These metals are thus classed as iron-chromium (Fe-Cr) alloys.
23 sie 2022 · The most widely used ferritic grade of stainless steel is SS430. With lower chromium content, SS409 is less corrosion-resistant. In contrast, SS439 resists corrosion better and is more stable in high temperatures. Depending on the alloy, ferritic stainless steels exhibit several beneficial properties. Corrosion Resistance
Ferritic stainless steels are essentially nickel-free. These materials contain very little carbon and are non-heat treatable, but exhibit superior corrosion resistance to martensitic stainless steels and possess good resistance to oxidation.
1 paź 2024 · There are more than 200 different grades of stainless steels, which are categorised in 4 main groups: austenitic, ferritic, martensitic and duplex. Austenitic A typical composition is 18 % chromium and 8 % nickel, as found in the popular AISI 304 grade.
