321 Stainless Steel Sheet is a chromium-nickel stainless-steel and also with the enhancement of titanium, 321 Stainless Steel Plate is resistant to intergranular deterioration. SS 321 is offered in Sheet, Strip, Plate, Foil (Shim) in numerous thicknesses. ASTM A240 Type 321 is an excellent choice for applications where temperature is a problem.

Chemical Composition of AISI ASTM ASME and UNS e.g. 304 being UNS S30400, 304L being UNS S30403 American Society of Mechanical Engineers (ASME) publish design codes and standards for pressure applications. ASME standards are generally based on the appropriate ASTM standards, but the standard numbers are preceded with the letters 'SA', rather than just the 'A' of the ASTM standards.
Chemical compositions of AISI (ASTM/ASME) and UNS Most ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers but also make reference, where appropriate to the more general AISI (American Iron and Steel Institute) grade designations. These grade numbering systems are widely used in the USA, where they originated and are recognised by most stainless steel

Standard Practice for Numbering Metals and Alloys (UNS)Sep 09, 2009 · ASTM on all matters pertaining to the UNS. It coordinates thinking on the format of each series of numbers and the administration of each by selected experts. It sets up ground rules for determining eligibility of any material for a UNS number, for requesting such numbers, and for appealing unfavorable rulings. It is the nal referee on matters of
