Key Features of 321 Stainless Steel L Channel
The two wings of 321 unequal angle steel have different lengths, which is more suitable for the installation of special-shaped frames and asymmetric load-bearing structures. It is often used in customized structures such as corner reinforcement, edge hemming, and equipment brackets.
High-temperature resistant 321 stainless steel angle can operate stably for a long time in a high-temperature environment of 800~870°C without precipitation of carbides, avoiding intergranular corrosion caused by high temperature. It is suitable for high-temperature structural parts such as heat exchangers, combustion chambers, and boiler supports. Its creep resistance is better than 304, and it is suitable for structural designs that withstand thermal stress.
