Classification
International standard ISO 513 classifies tool material
based on their reasonable applicability with respect
to the materials. ISCAR adopted this standard and
uses the same approach in tool development. In
accordance with the standard, the tool material
grades are characterized by a class of engineering
materials, to which a tool produced from the grade
can be applied successfully. Each class has a specific
identification letter and color:

steel and cast steel aluminum and other
except stainless steel non-ferrous metals and
with austenitic structure materials

austenitic and duplex
(austenitic/ferritic) stainless high-temperature
steel and cast steel superalloys and titanium

hard materials like
cast iron hardened steel and cast
iron, chilled cast iron

A classification number follows the letter to show the
hardness-toughness ratio of the grade according to
a conventional scale. Higher numbers indicate an
increase in grade toughness, while lower numbers
indicate an increase in grade hardness. Higher
numbers represent increasing feed and lower
numbers represent increasing speed.
