S31803 duplex tubes cannot be hardened by conventional standard heat treatment, though it is a work hardening steel. Duplex can be solution annealed at 1020-1100ºC, water quench.

Few major properties of grade S31803 tubes are excellent machinability, toughness and mechanical properties such as great tensile and imapact strength. This is one of the widely recommended seamless tube type beacuse of their highest immunity power in the entire 300 series. Duplex alloy seamless tubes contain chromium content around 21-23 percent, manganese content around 2 percent and silicon content around 1 percent max in their entire chemical composition. The duplex steel S31803 consists of around 40-50% ferrite in the annealed condition.
