What is 1008?

AISI/SAE 1008 is a very low-carbon (≤0.10 % C) plain carbon steel supplied mainly as cold-rolled or hot-rolled sheet and coil (ASTM A1008/A1011 CS/DS grades) and as cold-drawn wire and bar. It is chosen for its outstanding cold formability, deep-drawability and weldability at the lowest cost of any structural metal, and it takes paint, plating and zinc coatings readily. Limits are low strength, no hardenability by quenching (only carburizing or work hardening), gummy machining behaviour and essentially zero corrosion resistance when bare. 1008 has a density of 7.87 g/cm³ (0.284 lb/in³), heavier than 92% of steel grades. It melts at 1,495°C (2,723 °F). 1008 has a yield strength of 175 MPa (25.4 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of steel grades. Elongation at break is 30% and the elastic modulus is 200 GPa (29 Msi).

  • Stamped covers and enclosure panels
  • Sheet metal brackets
  • Deep-drawn appliance housings
  • Hot-dip galvanized ductwork and roofing sheet
  • Cold-drawn wire and cold-headed fasteners

Working with 1008

Is 1008 easy to machine?

Soft and gummy: use sharp positive-rake tools, high speed, generous coolant and chip breakers to avoid built-up edge and torn threads; expect ~55 % of 1212 and poor surface finish unless carburized or re-drawn.

Can 1008 be welded?

Excellent for all processes (RSW, MIG, TIG, laser, oxy-fuel) with no preheat or PWHT needed at any practical thickness; grind mill scale and remove zinc coating locally on galvanized stock.

Can 1008 be formed, bent or molded?

Best-in-class cold forming: bends to 0–1 t inside radius, deep drawing and roll forming; specify DDS/DDQ Al-killed for severe draws to avoid stretcher strain and ageing.

What surface finishes work on 1008?

Must be protected — iron/zinc phosphate + powder coat, e-coat, zinc or nickel plating, hot-dip galvanizing or black oxide; bare surfaces flash-rust within hours of degreasing.

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).

1008 — frequently asked

What is 1008 used for?

1008 is typically used for stamped covers and enclosure panels, sheet metal brackets, deep-drawn appliance housings, hot-dip galvanized ductwork and roofing sheet, cold-drawn wire and cold-headed fasteners and welded tube. In short: low-cost; easy cold-forming.

What is the yield strength of 1008?

1008 has a typical yield strength of 175 MPa (25.4 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of steel grades. Strength varies by condition: see the 8 listed tempers.

Is 1008 easy to machine?

Reasonably — machinability is rated fair (48/100, worse than 57% of steel grades). Soft and gummy: use sharp positive-rake tools, high speed, generous coolant and chip breakers to avoid built-up edge and torn threads; expect ~55 % of 1212 and poor surface finish unless carburized or re-drawn.

Can 1008 be welded?

Yes — weldability is rated excellent (95/100). Excellent for all processes (RSW, MIG, TIG, laser, oxy-fuel) with no preheat or PWHT needed at any practical thickness; grind mill scale and remove zinc coating locally on galvanized stock.

What surface finishes work on 1008?

Must be protected — iron/zinc phosphate + powder coat, e-coat, zinc or nickel plating, hot-dip galvanizing or black oxide; bare surfaces flash-rust within hours of degreasing.

Can 1008 be formed, bent or molded?

Best-in-class cold forming: bends to 0–1 t inside radius, deep drawing and roll forming; specify DDS/DDQ Al-killed for severe draws to avoid stretcher strain and ageing.

What is the maximum service temperature of 1008?

1008 is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between 1008-HR and 1008 CR-FH?

HR is the default condition — cheapest form, mill scale surface and looser thickness tolerance; use for weldments, brackets and parts that will be painted or machined. CR-FH: heavily work-hardened cold-rolled coil for flat, stiff, non-formed parts (shims, panels, strapping); bends will crack. Yield strength is 175 MPa in HR versus 500 MPa in CR-FH.
