      In the metalcasting arena, many grades of carbon and low alloy steel meet specific end-use requirements, such as structural strength, wear resistance, high temperature properties and corrosion resistance. While such material is generally ordered to ASTM requirements for steel castings, other specifications may be used.
      The most common ASTM specifications are:
      ASTM A 781/A 781M-97—Covers mandatory requirements for steel and alloy castings in general industrial use.
      ASTM A 703/A 703M-97—Covers common requirements that apply to steel castings for pressure-containing parts.  
      ASTM A 957-96—Covers requirements for steel and alloy castings produced via the investment casting process. 
      ASTM A 985-98—Covers common requirements for steel investment castings used in pressure-containing applications.
      The process and procedures most commonly specified by the customer in addition to material are heat treatment (which may enhance the properties of specific alloys) and welding. These processes have the greatest effect on casting metallurgical quality and serviceability, and both are routinely performed by steel casting facilities.
