Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars ( ASTM A276 ) or stainless steel plates for pressure vessels ( ASTM A240 ) or pipes ( ASTM A312 ).
The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard. The SAE steel grade system's correspondence to other alloy numbering systems, such as the ASTM-SAE unified numbering system (UNS), can be seen in cross-referencing tables (including the ones given below).
Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use.
Typical material properties for 2014 aluminium alloy are: [5] Density: 2.80 g/cm 3, or 175 lb/ft 3. Young's modulus: 73 GPa, or 11 Msi. Electrical conductivity: 34 to 50% IACS. Ultimate tensile strength: 190 to 480 MPa, or 28 to 70 ksi. Thermal Conductivity: 130 to 190 W/m-K. Thermal Expansion: 23 μm/m-K.
Alternate names and designations include AlMg3, 3.3535, and A95754. The alloy and its various tempers are covered by the following standards: [2] ASTM B 209: Standard Specification for Aluminium and Aluminium-Alloy Sheet and Plate; EN 485-2: Aluminium and aluminium alloys. Sheet, strip and plate. Mechanical properties

They provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, and higher strength than standard austenitic stainless steels such as A2/304 or A4/316. The main differences in composition, when compared with austenitic stainless steel is that duplex steels have a higher chromium content, 20–28% ...
Applications for superaustenitic stainless steel alloy AL-6XN include chemical processing, oil and gas, medical – sterilization and power generation [3] with specific applications identified in desalination, water piping systems. transformer cases in marine environments, food processing equipment, FGD scrubbers, reverse osmosis, and heat exchangers.
