COLD DRAWN (CDS)

General purpose seamless tubing, CDS allows selection of chemistry and rough tube size. Cold drawing produces higher physical properties without heat treating. Offers widest range of sizes and chemistries in mechanical tubing. Better tolerances and reduced machining allowances over HFS. Typically ordered as either OD and wall or OD and ID.

Machined parts, rollers, shafts, sleeves and cylinders.

HOT FINISHED (HFS)

HFS is available in larger diameters and heavier walls than cold drawn seamless. Hot finished is subject to surface imperfections and wider tolerances over CDS. Ordered to OD and wall only. May offer cost savings over parts presently using plate burn-outs, bar, or castings, due to less machining.

Rollers, heavily machined parts and sleeves.

COLD ROLLED

Excellent forming quality tubing. A513 Type 2 can be purchased with ID weld flash-in, flash controlled, or flash removed. It is produced from cold rolled steel in commercial quality or plating quality and is slightly more expensive than hot rolled as-welded.

Good for use in light structural applications, frames and furniture. Suitable for painting or plating, where surface finish is important.

DRAWN OVER MANDREL (DOM)

DOM is cold drawn through a die and over a mandrel resulting in improved surface finish, excellent concentricity and dimensional accuracy. Lower cost alternative to CDS with equal or superior physical properties.

Can be used for machined parts, rollers, shafts, sleeves and is most readily adaptable in cylinder applications.

COLD DRAWN

BUTTWELD

Excellent surface finish and machinability. Produced to closer tolerances than ERW, A513 Type 1 & 2. A512 is considered an acceptable low cost substitute for DOM and cold drawn seamless in non-pressure applications.

Can be used for structural applications, bushings, spacers, sleeves, or for many upsetting, flaring, and bending applications.
