They are used for equipment, structures and components exposed to moisture, chemicals or hygienic service, with different alloy compositions selected for corrosion resistance, strength, formability or weldability. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 88 designations · 15 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
