and may be used for the welded fabrications of
special assemblies (for example, rocker bearings).

Structural Steel Tubing
**************************************************************************
NOTE: ASTM A 500 tubing is available in Grades A,
B, C, and D with minimum yield strengths of 288,
290, 317, and 250 MPa 33, 42, 46, and 36 ksi for
round structural tubing and 269, 317, 345, and 250
MPa 39, 46, 50, and 36 ksi for shaped structural
tubing, respectively. ASTM A 500 tubing may not be
suitable for dynamically loaded structures or
applications requiring notch strength. ASTM A 618
is available in Grades I (a or b), II, or III.
Grades I and II have a minimum yield strength of 315
to 345 MPa 46 to 50 ksi (depending on size); Grade
III has a minimum yield strength of 345 MPa 50 ksi.
ASTM A 618, Grades Ia and Ib, have a corrosion
resistance four times that of carbon steel in
non-marine environments; Grade II has a corrosion
non-marine environments; and the corrosion
resistance of Grade III can be increased by
specifying a minimum copper percentage of 0.2
percent. For steel tubing, normally only ASTM A
500, Grade B is stocked. ASTM A 618 tubing is
available ASTM A 325M ASTM A 325 and ASTM A 490M
ASTM A 490 only in round shapes.
