Multipurpose Steel · Cold Rolled Sheet
Steel SPCC
Steel SPCC is a multipurpose steel steel — common commercial cold-rolled. Typical values: 140 MPa yield, 7.85 g/cm³, rated to 400 °C. Available for Sheet metal at FabDigit.
Properties
Typical room-temperature values in the HR (hot Rolled) condition. Metric first, imperial in gray. The bars show where SPCC sits against the other 317 steel grades in the catalog.

Heat treatment and post-processing
Operations FabDigit's suppliers routinely run on SPCC, ranked by how often they make sense for this grade.
Heat treatment
| Quench & Temperrecommended | Achieve target hardness with controlled toughness28–55 HRC |
|---|---|
| Full Anneal | Restore ductility; relieve residual stress; coarsen grain |
| Stress Relief | Reduce residual stress without changing structure |
| Normalize | Refine grain; reset prior cold-work |
| Induction Hardening | Local surface hardening via induction50–62 HRC |
| Process Anneal | Reduce stress between cold-work steps |
| Flame Hardening | Local surface hardening via direct flame50–60 HRC |
| Case Harden (Carburize) | Diffuse C into surface; harden case to 60+ HRC58–64 HRC |

Property data is compiled from published supplier and standards handbooks and normalised for comparison; hardness values on non-Brinell scales are converted approximately for charting only. Manufacturability limits are FabDigit quote-engine defaults and may be relaxed by engineering review. Nothing on this page is a certification — request mill certs, CoC or material test reports with your order.
