The current international standard specifies the technical delivery conditions for corrosion-resistant seamless tubes for
use as casing, tubing and coupling stock.

The current international standard applies to the following four tube groups

Group 1, comprising stainless alloys with a martensitic or martensitic/ferritic structure;

Group 2, comprising stainless steels with a ferritic-austenitic structure, such as duplex and super duplex stainless steels;

Group 3, comprising stainless alloys with an austenitic (iron based) structure;

Group 4 , comprising nickel based stainless alloys with an austenitic (nickel based) structure.
