ASTM A686 - 92(2010)

ASTM A686
Abstract

This specification covers chemical, mechanical, and physical requirements for available wrought carbon Tool steel products. These products, which include hot- or cold-finished bar, plate, Pipe Fitting, flange, steel pipe, or Forgings, are normally fabricated into tools, dies, or fixtures. The selection of a material for a particular application will depend upon design, service conditions, and desired properties. An analysis of each heat of steel shall be made by the manufacturer to determine the percentage of the elements specified and these values shall conform to the chemical composition specified by the reference material. The hardness of the specimen after the specified heat treatment shall meet the minimum hardness value for the particular type of steel prescribed by the reference material. Rockwell C tests should be used where possible but light load tests may be necessary on thin specimens. The macrostructure of a specimen representing the entire cross-sectional area in the annealed condition shall be prepared in accordance with the reference material. It shall exhibit a structure free of excessive porosity, segregation, slag, dirt or other nonmetallic inclusions, pipes, checks, cracks, and other injurious defects.

It is informational only and not an official part of the standard; the full text of the Standard itself must be referred to for its use and application.
