ASTM A793 Specification

The ASTM A793 specification covers stainless steel plate, which  is commonly used in:

  • engine rooms
  • galley spaces
  • washrooms
  • machinery spaces

Additionally, it can be used for smaller spacing such as gun platforms,  ladder treads,and deck treads. ASTM A793 comes in several steel grades, such as Type 304, 304L, 316, 316L . Its chemical composition requirements include carbon, manganese, phosphorus, sulfur, silicon, nitrogen, nickel, chromium, and molybdenum as determined by heat analysis.

Annealing is the final heat treatment to which the ASTM A793 is subjected. Mechanical properties are tested by two longitudinal cold bend tests, ensuring the raised figure does not crack or fracture. A magnetic permeability test is preformed, in order to ensure the specified magnetic permeability indicator meets the necessary requirements.
