Stainless Steel They can be hardened by cold work, but this is rarely practiced. 304 is the most commonly used austenitic stainless steel. Hardness can be obtained through cold-working. The chemical composition of grade 310 and grade 310S stainless steel are summarised in the following table. Ferritic stainless steel forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and precipitation hardened. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened).Its primary crystalline structure is austenite (face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes them essentially non-magnetic. Duplex 5. stainless steel Austenitic steels form the largest portion of the global stainless steel market and are often used in food processing equipment, kitchen utensils, and piping. Ferritic stainless steel alloys can generally be classified into five groups, three families of standard grades (Groups 1 to 3) and two families of specialty grade steels (Groups 4 and 5). DESIGN GUIDELINES FOR THE SELECTION AND USE OF The best-known of these are Type 304, which has 8% nickel and Type 316, which has 11%. Stainless Grade data, specifications and properties are inlcuded for stainless steel. Ferritic stainless steel alloys can generally be classified into five groups, three families of standard grades (Groups 1 to 3) and two families of specialty grade steels (Groups 4 and 5). Ferritic stainless steel We have 33 austenitic stainless steel grades and options available in strip and/or wire to meet a wide variety of purposes. Table 1. The rest of the makeup is defined by various alloying elements, which control the microstructure of the alloy. Core range contains austenitic and ferritic stainless steel products for medium corrosive environments. Welding of Austenitic Stainless Steel Duplex 5. Austenitic stainless steel has austenite as the primary microstructure. Ferritic stainless steel, on the other hand, has higher thermal conductivity. Austenitic Stainless Steel Applications. Duplex (Ferritic-Austenitic) Stainless Steels. Table 1. Ferritic Stainless Steel 304L is a variation that has a lower carbon content. Hardenability: As mentioned earlier, austenitic stainless steel is not hardenable by heat treatment.

Stainless Steel Stainless Steel Characteristics Stainless Steel 304 finds use in a variety of industries, including automotive, food and beverage, nuclear, and shipping, while 304L is generally used in welding applications. Steel Stainless Steel All stainless steels are iron-based alloys containing at least 10.5% chromium. Advantages and Disadvantages of Stainless Steel Grade data, specifications and properties are inlcuded for stainless steel. Below are the different grades of stainless steel 316. Compared with ferritic stainless steels, austenitic types respond better to cold working. SAE steel grades Martensitic 4. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in All stainless steels are iron-based alloys containing at least 10.5% chromium. They also have a tensile strength of between 80,000 - 150,000 PSI. While standard ferritic steels are, by far, the largest consumer group in terms of tonnage, demand for specialty grade stainless steels is increasing steadily. Stainless Steel Grades There are 150 grades of steel alloy, which are classified in 4 different groups according to their varying corrosion resistances and mechanical properties. Chemcial Composition of Grade 310/310S Stainless Steel . They can be hardened by cold work, but this is rarely practiced. Ferritic stainless steel forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and precipitation hardened. The majority are classified into five major groups in the family of stainless steels: austenitic, ferritic, martensitic, duplex, and precipitation-hardening. Sometimes referred to as 18/8 because of its 18% chromium and 8% nickel, it is used in kitchen equipment, cutlery, food processing equipment, and structural components in the automotive and aerospace industries. Low carbon chromium stainless steel with chromium of more than 14%, chromium stainless steel with 27% and above chromium and any carbon content, and on the basis of the above ingredients add molybdenum, titanium, niobium, silicon, aluminum, tungsten, vanadium, etc. Austenitic 2.
