Steel Materials according to ASTM standard
Dimensions from carbon steel pipes are defined in the ASME B31.10M standard, dimensions for stainless steel pipe are defined in the ASME B31.19M standard. The material qualities for these pipes are defined in the ASTM standards. 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, et cetera, 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 et cetera. Below you will find as an example a table with chemical requirements for pipe according to ASTM A106 Grade A,B,C, and a table with frequent Grades, arranged on pipe and pipe-components, which belong together as a group. As you may be have noted, in the table below, ASTM A105 has no Grade. Sometimes ASTM A105N is describe...
