Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened [ 1] ). Its primary crystalline structure is austenite ( face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes them essentially non ...
Stainless steel, also known as inox, corrosion-resistant steel ( CRES ), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results ...
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
EN 10027-1 steel grade designation system. European standard steel grade names fall into two categories: [1] Steel specified by purpose of use and mechanical properties. Steel specified by chemical composition. The inclusion of a letter 'G' before the code indicates the steel is specified in the form of a casting.
X46Cr13. X46Cr13 is the European Norm name for a common martensitic stainless steel with the numeric name 1.4034. It is equivalent to American Iron and Steel Institute standard 420C. It has the highest carbon content of the SAE 420 series. [ 1][ 2][ 3]
SAE 904L stainless steel. 904L is an austenitic stainless steel. It is harder than 316L, [ 1] and its molybdenum addition gives it superior resistance to localized attack ( pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all ...
SAE 304 stainless steel is the most common stainless steel. It is an alloy of iron, carbon, chromium and nickel. It is an austenitic stainless steel, and is therefore not magnetic. It is less electrically and thermally conductive than carbon steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in ...
