Standard Specification for Aluminum-Alloy 6061-T6

ASTM B308/B308M specification covers extruded 6061-T6 aluminum-alloy standard structural profiles that are limited to I-beams H-beams, channels, angles, tees and zees. They are sensitive to high temperatures, when reach about 200-250°C, they will lose some of their strength. However, their strength can be increased at subzero temperatures. They have good corrosion resistance feature as stainless steel.

Inspection of Alu 6061 T6 Flanges and Fittings

For the Slip-on flanges. we inspected the outside diameter, iameter at bease of Hub, OD of raised face, bore and thickness and length thru hub.

Alu 6061 T6 Flange

For butt weld fittings, we measured the outside diameter and thickness, also the degree for elbows, height of tees and concentric reducers.
