Heat treatment of stainless pipes
- 15 Downloads
The recrystallization temperature of rolled pipes is lower than that of drawn pipes due to the greater deformation of the former.
The strength properties after recrystallization are higher for rolled than for drawn pipes which makes it possible to heat the former 100°C higher.
The temperature of heat treatment of rolled stainless pipes (1100–1150°C) is 300–400°C higher than the recrystallization temperature and ensures complete removal of hardening.
The temperature of heat treatment of drawn stainless pipes (1000–1050°C) coincides with recrystallization temperatures (950–1050°C). Careful control of metal temperature is necessary in order to ensure complete removal of hardening in drawn pipes during heat treatment.
