They are used for heavily loaded components such as shafts, gears, fasteners and structural machine parts where resistance to mechanical stress is required. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 92 designations · 26 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## Physical & mechanical properties Density 7,85 g/cm³ Exact Transformation point Ac1 726 °C Exact Transformation point Ac3 765 °C Exact · Ac3(Acm) Transformation point Ar3 741 °C Exact · Ar3(Arcm) Transformation point Ar1 689 °C Exact Weldability not suitable for welding As published: is not used.

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