This alloy exhibits properties that prove to be extremely beneficial for many industries. It is considerably corrosion resistant. It is resistant to crevices formation in chloride environments up to a temperature of 60 degree Celsius. Grade 321H is the higher carbon variant of this alloy, which has higher strength at higher temperature. This grade of steel has a good thermal resistance, functioning the best at a temperature range of 425-900 degree Celsius. 321H is more suitable for high temperature structural applications as it has higher hot strength. They have excellent weldability with all standard fusion methods, with or without filler metals.
It has as many applications as the beneficial properties. Some of them include its use in manufacturing aircraft exhaust manifolds. They are also used in manufacturing expansion joints and bellows. Even furnace components are manufactured using this alloy. Because of good thermal resistance, they are used in heat exchangers and heating element tubes. It is also used in spiral welded tubes for burner pipes and flues.
