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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: C, Mn, Si, Ni, Cr, Mo. ## Physical & mechanical properties An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Heat treatment **NB /T 47008-2017** Single operation t≤300 - Tempering 680 °C Supply condition - Normalizing and Tempering d≤100 - Quenching and Tempering d=30 - Spheroidize annealing Plate and Strip Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
