Seamless mechanical tubing is manufactured from carbon and alloy steels for structural asfm other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors.

Micro alloys available upon request. Reduce the weight of your product while increasing your physical requirements. The latter sizes and hot finished seamless stocks are carried in warehouse to OD and wall tolerances.


Tolerances are applicable only to two dimensions length excepted.

ASTM A519 Seamless Mechanical Tubing

However, for a nominal OD of 1. Hence, any order of tubes might vary in the entire lot as low as 0. Nominal Temperature Without Accelerated Cooling.

NOTE — Tubing having a wall thickness less than 3 percent of the outside diameter cannot be straightened properly without a certain amount of distortion. Camber, or out-of-straightness, tolerances generally do not exceed the amounts shown for lengths of 22 feet and under.

The camber is measured for any three feet of length with a three foot straightedge and the use of a feeler gage. The total camber — maximum curvature in the total length of the tube — is determined by rolling the tube on a surface plate and measuring the concavity with a feeler gage.

ASTM A Seamless Tube, ASTM A Mechanical Tubing, ASTM AM AISI Tubing.

When the machined length of a tube extends more than three inches from the chuck or other holding mechanism, the possibility that the tube may be cambered must be taken into consideration. Allowance for camber must be made for any machined length proportional to the tolerances shown. Tubes with lighter or heavier walls than shown, and soft annealed or hardened tubes, present more than normal straightening difficulties, and the camber tolerance a5119 of such tubes usually are mutually agreed upon by the purchaser and the producer.


Nominal Yield Strength psi. Nominal Ultimate Strength psi. Outside Diameter Size Range in.

Wall Thickness as Percent of OD. ID Up To 1.

ID Tolerances apply to dimensions 0. See also Footnote B. Footnote A is not applicable. Therefore, for those tubes, the inside diameter is goverened by the outside diameter tolerance shown in thiis table and the wall thicnkess tolerances shown in Table s519.
