Product Description

ASTM A334 Gr1 Gr6 Welded Carbon Steel Tube

Sope:

1 This specification covers several grades of minimum-wall-thickness, seamless and welded,

carbon and alloy-steel tubes intended for use at low temperatures. Some product sizes may not be

available under this specification because heavier wall thicknesses have an adverse affect on

low-temperature impact properties.

2 Supplementary Requirement S1 of an optional nature is provided. This shall apply only when

specified by the purchaser. NOTE 1 For tubing smaller than 1/2 in. [12.7 mm] in outside diameter,

the elongation values given for strip specimens in Table 1 shall apply. Mechanical property

requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in outside diameter and with

a wall thickness under 0.015 in. [0.4 mm].
