Who is ASTM? ASTM Standards !Development of standards !
Services of ASTM International . Use of standards.Annual book of ASTM .
These ASTM
standards, define the specific manufacturing
process of the material and determine the
exact chemical composition of pipes,
fittings and flanges, through percentages of
the permitted quantities of carbon,
magnesium, nickel, etc., and are indicated
by "Grade".
For example, a carbon steel pipe can be
identified with Grade A or B, a
stainless-steel pipe with Grade TP304 or
Grade TP321 etc..
Below you will find as an example a table with
chemical requirements for fittings ASTM A403
Grade WP304, WP304L, WP316L and a table with
frequent Grades, arranged on pipe and
pipe-components, which belong together as a
group.
