the 200 series of stainless steels
The 200 series stainless steels are,consequently,characterized by their nitrogen and manganese content.Production and demand for low-nickel stainless steels surged in the 1980s as nickel prices soared and,again,efforts were made to reduce use of the metal.200 series stainless production - Stainless Steel WorldChina-based Jiuquan Iron Steel Group has started a test run of 200 series stainless production.However,Jiuquan will not yet start massive production of 200 series stainless,due in part to the Chinese Government not encouraging such an action.200 series stainless steels - high manganese (CrMn)
Stainless steel alloys resist corrosion,maintain their strength at high temperatures and are easy to maintain.They most commonly include chromium,nickel and molybdenum.Stainless steel alloys are used predominantly in the automotive,aerospace and construction industries.302 Stainless Steel Austenitic,non-magnetic,extremely tough and ductile,302 Stainless Steel is one of the more 300 Series Stainless Steel vs 400 Series Which Is Best Generally,400 series stainless steel refers to 430 stainless steel as it is the most widely used 400 series alloy.This family of stainless steel contains 11% chromium and 1% manganese.It should also be noted that 400 series stainless steel has a higher carbon content than 300 series.400 Series Stainless - Penn StainlessThe 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase,above the 300 series group.The 400 series is susceptible to rust and corrosion under some conditions.Heat-treating will harden the 400 series.The 400 series of stainless steels have higher carbon content,giving it a martensitic crystalline
The 200 series,developed to get around the high price of nickel,replaces some nickel content with manganese and nitrogen.The most commonly used austenitic grade is SS304.With its composition of 18 percent chromium and 8 percent nickel,it is sometimes referred to as 18-8 stainless.Austenitic Chromium-Manganese Stainless Steels A The 200 series of stainless steels was de-veloped in the early 1930s.Although the first chemical analyses were of the 205 kind (Ni content close to 1 % and stabilisation of the austenitic phase by simultaneous high manganese and nitrogen additions seeAustenitic Stainless Steels - Characteristics and UsesAustenitic Stainless SteelStainless Steel Type 304Properties of Austenitic Stainless SteelsHardness of Austenitic Stainless SteelsThermal Properties of Austenitic Stainless SteelsAustenitic stainless steels contain between 16 and 25% of chromium and can also contain nitrogen in solution,both of which contribute to their relatively high corrosion resistance.Austenitic stainless steels are classified with AISI 200- or 300-series designations; the 300-series grades are chromium-nickel alloys,and the 200-series represent a set of compositions in which manganese and/or nitrogen replace some of the nickel.Austenitic stainless steels have the best corrosion resistance of all stainless steelsSee more on nuclear-power.netStainless Steel Grade Manufacturers IQS DirectoryOf all the different series,the 200,300 and 400 series are the most common.Stainless steel is graded through consideration of the environment that it will be assigned to.The typical stainless steel grading system used for stainless steel is the Society of Automotive Engineers (SAE) Grades,which is designated by the SAE,and the UNS grades.
Dec 15,2015·AUSTENITIC STAINLESS STEELS Austenitic stainless steels are the most specified grades produced because of their excellent formability and corrosion resistance.All 200 and 300 series steels are austenitic,and contain 15% to 30% chromium and 2% to 20% nickel for enhanced surface quality,formability,and increased corrosion and wear resistance.Grade Chemical composition (wt%) Chemical composition (wt%) Chemical composition (wt%) Chemical composition (wt%) AISI UNS Cr Ni N 304 S30400 18.0 - 20.0 8.0 - 10.5 0.10 max 201 S20100 16.0 - 18.0 3.5 - 5.5 0.25 max 202 S20200 17.0 - 19.0 4.0 - 6.0 0.25 max 1 more rows ·200-Series Stainless Steel This series of stainless steel has 17-percent chromium,4-percent nickel and 7-percent manganese added to steel.The 200-series steels have an austenitic structure.This refers to the crystal structure of the material.History Properties Applications AdviceNew 200-series steels November 2005 Austenitic-Ferritic (Duplex) These stainless steels,which contain some nickel,have a roughly 50% ferritic and 50% austenitic microstructure and are both strong and ductile.They are mostly used in the process industry and in seawater applications.Martensitic Like ferritic grades,martensitic grades

Jun 10,2014·200 series You may often find stainless steel food containers made from 200 series stainless steel.These are typically less expensive than 304 grade as manufacturers essentially substitute manganese for nickel.Although food safe,they are not as resistant to corrosion and not as high quality as 304 grade.
