Classification of steel:According to composition:Steel can be classified according to the composition. The most commercial steel can be classified into two groups 1. carbon steel 2. alloy steel 2 Carbon steel:This type of steel has less than 1 percent of carbon and traces of manganese ,sulfur ,silicon ,phosphorus .The properties and

Aerospace Stainless Steel Distributor SupplierStainless Steel Classifications . There are four basic classes of stainless steels, so designated for the metallurgical conditions of the steels:Class I:Martensitic - Heat treatable, Straight Chromium. This class is so named for the man, Martens, who first examined metals microscopically.


Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2. The AISI numbering system:namely 200, Ferritic Stainless Steel - an overview ScienceDirect TopicsFerritic steels, Types 430 and 434, are resistant to SCC in MgCl 2 at 140°C. High purity ferritic stainless steels are subjected to SCC in boiling 30% sodium hydroxide in tests exceeding 1000 h and in 42% MgCl2 in a sensitized condition. Types 430 and 446 stainless steels are subject to chloride SCC in the welded conditions.

of the high-performance stainless steels. There are three primary classifications within the high-performance stainless steels. They are the austenitic, ferritic, and duplex (austenitic-ferritic) families. The stainless steels in each family have general similarities, but there is also a wide range of corrosion resistance and other characteristics. Introduction and classification - Stainless steels CourseraStainless steels. This course covers from the fundamental aspects to the production, physical metallurgy, corrosion and mechanical properties of stainless steels. Detailed explanation on the microstructures, corrosion and mechanical properties of different types of stainless steels will be treated. Introduction and classification 12:06.

Stainless Steel Pipe Fittings McMaster-Carr

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you wont have to worry about matching exact threads when youre on the job. Stainless Steel The Four Types of Steel Metal SupermarketsMar 23, 2015 · Stainless steel is about 200 times more resistant to corrosion than mild steel. Stainless steel can be divided into five groups:Austenitic :Austenitic steels form the largest portion of the global stainless steel market and few of its versatile usages would be food processing equipment, kitchen utensils and medical equipment.

Stainless Steel:Properties, Examples and Applications

  • CharacteristicsDurabilityClassificationPropertiesTreatmentConstructionUsageTypesAustenitic stainless steels are split into two subcategories:the 300 series and 200 series. For the 300 series, the austenitic structure is achieved via the addition of nickel, whereas for the 200 series, this is achieved primarily via the addition of manganese and nitrogen.Stainless Steel - Comparing International StandardsStainless Steel Classifications - Stainless steels are commonly grouped into martensitic stainless steels, ferritic stainless steels, austenitic stainless steels, duplex (ferritic-austenitic) stainless steels, and precipitation-hardening stainless steels Stainless Steels - Introduction To The Grades And Families
    • The Families of Stainless SteelsAustenitic Stainless SteelsFerritic Stainless SteelsMartensitic Stainless SteelsDuplex Stainless SteelsPrecipitation Hardening Stainless SteelsCharacteristics of Stainless SteelsStandard ClassificationsThere are many different varieties of stainless steel and the American Iron and Steel Institute (AISI) in the past designated some as standard compositions, resulting in the commonly used three digit numbering system. This role has now been taken over by the SAE and ASTM, who allocate 1-letter + 5-digit UNS numbers to new grades. The full range of these standard stainless steels is contained in the Iron and Steel Society (ISS) "Steel Products Manual for Stainless Steels", and in the SAE/ASTM handbooTypes and grades of Stainless Steel Plate // Stainless
      • Austenitic GradesMartensitic GradesFerritic GradesDuplex GradesPrecipitation Hardening GradesSuper Alloy GradesAustenitic grades are those alloys which are commonly in use for stainless applications. The austenitic grades are not magnetic. The most common austenitic alloys are iron-chromium-nickel steels and are widely known as the 300 series. The austenitic stainless steels, because of their high chromium and nickel content, are the most corrosion resistant of the stainless group providing unusually fine mechanical properties. They cannot be hardened by heat treatment, but can be hardened significantly by cold-workiAISI Type 302 Stainless Steel Properties, SS302 AISI Type 302 Stainless Steel (UNS S30200) Type 302 stainless steel is basically a higher carbon version of type 304, a variant of 18-8 stainless steel. Its carbon content is 0.15%, and the minimum chromium content is only 1% less than 304. Grade 302 stainless steel spring wire (specified in ASTM A313) has high heat resistance and good

        Stainless steels are routinely produced with strengths from 100 MPa to more than 1 GPa. Knowledge of the relative stabilities of the b.c.c. and f.c.c. structures of iron alloys is therefore of prime concern. The history of stainless steels started with a martensitic steel (12Cr-0.1C wt%) in Sheffield, UK and the austenitic 18Cr-8Ni wt% in Germany.Stainless Steel Characteristics:Grades, Properties Ferritic steels are the 400 Grade stainless steels noted for their high chromium content, which can range from 10.5% to 27%. They have magnetic properties, too, offers good ductility, tensile-property stability, and resistance to corrosion, thermal fatigue, and stress-corrosion cracking. Ferritic Stainless Steel
