For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension. This tolerance may be increased 50 percent when applied to the smaller dimension, if the ratio of cross sectional dimensions is between 1.5 and 3, and 100 percent when the ratio exceeds 3. WLL THICKNESS Maximum llowable Variation % (wall thickness is to be measured at the center of the flat, exclusive of the weld area, and not at corners) CORNER RDII The radius of any outside corner shall not exceed three times the specified wall thickness. TWIST LONGEST OUTSIDE DIMENSION MXIMUM TWIST PER 3 FEET OF LENGTH 2 to 2½% inclusive over 2½% to 4 inclusive over 4 to 6 inclusive over 6 to 8 inclusive over STRIGHTNESS: Permissible variation shall be 1/8 times the number of feet of total length divided by 5:.125 x (total length) 5 SQURENESS OF SIDES: djacent sides may deviate from 90 degrees by a tolerance of plus or minus 2 degrees imum. FLSH: Structural tubing usually is supplied flash-in. The height of the flash will vary with the wall thickness of the tube.

Low carbon type 304 where greater resistance to carbide precipitation is desired. Carbon modified for improved high temperature strength. High resistance to scaling and oxidation up to 2000 F. etter corrosion resistance than type 304 in reducing media. Good hi-temp strength Low carbon type 316 where greater resistance to carbide precipitation is desired. Carbon modified for improved temperature strength. Similar to type 316 but with better corrosion resistance and creep strength Titanium stabilized against carbide precipitation. Similar properties to type 304. Columbium and tantalum stabilized against carbide precipitation. High strength-to-weight ratio. Good corrosion resistance. Hardenable by heat treatment. Free machining. Moderate corrosion resistance.
