KS steel grades — 823 designations
Every grade designated under KS, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Unless marked, every name here is an asserted identity — the same grade under this standard’s own designation. 3 of 50 rows differ and carry an “Indicative” mark.

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Withdrawn — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
