PN steel grades — 635 designations — Page 4
Every grade designated under PN, with the material number it maps to, what kind of steel it is, its carbon window and how many other standards carry it. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is an indicative cross-reference, not an asserted identity: the grades are close, not interchangeable. Check the composition before you substitute.

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Withdrawn — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
