Steel 1008 cold-rolled (CRS)
1008 cold-rolled steel is a low-carbon steel, 0.10% carbon maximum, sold as annealed sheet and coil to ASTM A1008. It is the default material for stampings and deep drawn parts because it forms well, welds easily and costs little. Typical yield strength is 20–40 ksi (140–275 MPa). It rusts bare, so plan on zinc plating, e-coat or powder coat.

When should you use 1008 CRS?
Strengths
- Forms and draws well in CS (commercial) and DS (drawing steel) designations
- Lowest-cost sheet steel for high-volume parts
- Spot, MIG and projection welds easily
- Clean cold-rolled surface plates, paints and powder coats well
- Also drawn into low-carbon wire for wire forms
Watch for
- Rusts quickly bare; needs a coating
- Low strength; use A1008 SS or HSLAS grades when strength matters
- Cannot be through-hardened; carbonitride for a wear-resistant case
Typical parts
- Brackets, clips and mounting straps
- Deep drawn cups, cans and motor housings
- Appliance panels and chassis
- Electrical boxes and enclosures
- Washers and stamped hardware
- Wire racks, guards and shelving

Stamping in 1008 CRSShort- to medium-run stampings: brackets, clips, shields, and plates cut and formed from sheet or coil in a press.
Deep draw in 1008 CRSOne-piece cups, cans, shells, and housings drawn from flat blanks, with depth that can exceed the diameter.
Sheet metal in 1008 CRSLaser-cut, punched, bent, and welded sheet metal enclosures, brackets, and chassis with no hard tooling.
Springs & wire forms in 1008 CRSCompression, extension, and torsion springs, wire forms, and fourslide clips made from round wire and flat strip.
Offshore sourcing in 1008 CRSParts made by vetted overseas manufacturers, with landed-cost analysis, quality control, and logistics managed.
What does a part in 1008 CRS cost?
A representative part, stamping. Raw material at about $1.30/kg is one line of it; process time and tooling usually matter more.

1008 CRS questions
What is the difference between CS and DS steel?
Under ASTM A1008, CS (commercial steel) suits bending and moderate forming. DS (drawing steel) has tighter chemistry and lower yield for deeper draws. DDS and EDDS grades go further for severe draws. Give the stamper the draw depth and they will pick the grade.
Cold-rolled vs hot-rolled steel for stampings?
Cold-rolled holds tighter thickness tolerance, has a smooth scale-free surface and forms more consistently, so it is the choice for visible or precise parts. Hot-rolled pickled and oiled sheet (ASTM A1011 HRPO) costs less for thicker, non-cosmetic parts.
Can 1008 steel be hardened?
Not by quench and temper; it has too little carbon. Carburizing or carbonitriding adds a hard case of about 0.003–0.020 in (0.08–0.5 mm) for wear parts. For a through-hardened stamping, use 1050, 1075 or 1095 spring steel strip.
What coating should I use on 1008 stampings?
Zinc plating for small parts in indoor or mild service, e-coat for uniform protection on complex shapes, and powder coat for color and outdoor durability. Zinc-nickel is the upgrade when parts need several hundred hours of salt spray.
