Structural Steel - an overview ScienceDirect Topics

Steel can be classified as carbon steel,high-strength low-alloy (HSLA) steel,heat-treated carbon steel,and heat-treated constructional alloy steel.Structural steel under the prolonged influence of operational factors such as pressure,temperature,cyclic loads,radiation,and the environment can lead to embrittlement as a result of thermal Standard Specification for General Requirements for Steel A543/A543M Specification for Pressure Vessel Plates,Alloy Steel,Quenched and Tempered Nickel-Chromium-Molybdenum.A553/A553M Specification for Pressure Vessel Plates,Alloy Steel,Quenched and Tempered 7,8,and 9 % Nickel.A562/A562M Specification for Pressure Vessel Plates,Carbon Steel,Manganese-Titanium for Glass or Diffused Metallic Stainless steel for potable water treatment plants (PWTP)Various Stainless Steel Types The low carbon L grades have a maximum of 0.03% carbon and should be used for fittings,and mechanical joints pose few problems in low chloride potable waters.Naturally occurring crevices from sediment can be re-duced by high flow rates.When design or operating
