Values for the S condition
SPCE tempers and conditions
SPCE is supplied in 3 conditions, soft to hard. S is the default FabDigit quotes; the values on this page are for it.
Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Solution annealed | Softest condition, lowest yield strength; choose when maximum drawability matters and stretcher-strain (Lüders) marks on the part surface are acceptable or removed by later forming. | 140 | 285 | 44 | 85 HB | 11 % IACS |
Non-ageing extra deep drawing quality | Ti/Nb-stabilised or specially processed non-ageing version; specify when parts are formed months after delivery and stretcher strains / yield-point return must be guaranteed absent (typically warranted 6 months). | 150 | 290 | 44 | 87 HB | 11 % IACS |
SDefault Standard temper | Default stocked condition: fully annealed then temper-rolled to suppress yield-point elongation and set surface roughness for deep drawing. | 155 | 295 | 42 | 90 HB | 11 % IACS |

What is SPCE?
SPCE is JIS extra-deep-drawing quality cold-rolled carbon steel sheet to JIS G 3141, corresponding to European DC05, with very low carbon for maximum drawability. It is used for the most demanding drawing operations, offering r ≈ 1.8–2.2, n ≈ 0.22, 42 % elongation and 155 MPa yield in annealed, skin-passed and non-aging SPCEN tempers as coil, sheet and blanks. Low yield strength limits dent resistance and load-bearing use, and the bare surface has no corrosion resistance. SPCD/DC04 is cheaper for less severe draws; DC06 is the IF alternative when non-aging behaviour must be guaranteed. SPCE has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,500°C (2,732 °F). SPCE has a yield strength of 155 MPa (22.5 ksi) and a tensile strength of 295 MPa (42.8 ksi) — weaker than 100% of steel grades. Elongation at break is 42% and the elastic modulus is 205 GPa (29.7 Msi).

Chemical & Environmental3
Corrosion resistance is not recommended (10/100), worse than 86% of steel grades.
Sustainability4
Producing a kilogram of SPCE takes about 30 MJ of energy and emits 2.3 kg of CO₂ — more than 56% of steel grades. Typical recycled content is 25%.
Manufacturability7
SPCE's machinability is fair (48/100, worse than 57% of steel grades); weldability excellent (95/100); formability excellent (98/100).

Working with SPCE
Is SPCE easy to machine?
Rarely machined; soft ferrite is gummy — use sharp positive-rake tools, high speed and coolant, expect burrs on punched/blanked edges.
Can SPCE be welded?
Excellent for resistance spot, projection, laser and MIG welding thanks to very low carbon; no preheat or PWHT needed.
Can SPCE be formed, bent or molded?
Designed for the most severe deep draws (r ≈ 1.8–2.2, n ≈ 0.22): use matched-die draws with proper blank-holder force and drawing oil; use SPCEN if storage before forming exceeds a few months to avoid stretcher strains.
SPCE chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on SPCE?
Must be protected — zinc or Zn-Ni electroplating, hot-dip galvanizing, zinc-phosphate + e-coat/powder paint; surface is well suited to Class-A painted panels.
Surface treatments FabDigit runs on steel parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

SPCE — frequently asked
What is SPCE used for?
SPCE is typically used for complex drawn parts, automotive body panels and sink basins. In short: extra-deep-drawing JIS grade; DC05 equivalent; class-A paintable surface.
What is the yield strength of SPCE?
SPCE has a typical yield strength of 155 MPa (22.5 ksi) and a tensile strength of 295 MPa (42.8 ksi) — weaker than 100% of steel grades. Strength varies by condition: see the 3 listed tempers.
Is SPCE easy to machine?
Reasonably — machinability is rated fair (48/100, worse than 57% of steel grades). Rarely machined; soft ferrite is gummy — use sharp positive-rake tools, high speed and coolant, expect burrs on punched/blanked edges.
Can SPCE be welded?
Yes — weldability is rated excellent (95/100). Excellent for resistance spot, projection, laser and MIG welding thanks to very low carbon; no preheat or PWHT needed.
What surface finishes work on SPCE?
Must be protected — zinc or Zn-Ni electroplating, hot-dip galvanizing, zinc-phosphate + e-coat/powder paint; surface is well suited to Class-A painted panels.
Can SPCE be formed, bent or molded?
Designed for the most severe deep draws (r ≈ 1.8–2.2, n ≈ 0.22): use matched-die draws with proper blank-holder force and drawing oil; use SPCEN if storage before forming exceeds a few months to avoid stretcher strains.
What is the maximum service temperature of SPCE?
SPCE is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SPCE-S and SPCE-A?
S is the default condition — default stocked condition: fully annealed then temper-rolled to suppress yield-point elongation and set surface roughness for deep drawing. A: softest condition, lowest yield strength; choose when maximum drawability matters and stretcher-strain (Lüders) marks on the part surface are acceptable or removed by later forming. Yield strength is 155 MPa in S versus 140 MPa in A.
