Heat Treatment For 316 SS Cold Rolled Pipe
| Heat treatment | Heating temperature | Purposes | Suitable steel | Scope of application |
| Full annealing |
Above Ac3 From 20 to 40℃ |
Refining grains, eliminating internal stress, network and Widmannstatten structures and reducing hardnes | Hyposteel | Heat treatment of tube billets and finished pipes |
| Partial annealing |
From Ac1 to Ac3 From780 to 800℃ From Ac1 to Acm From750 to 770℃ |
Improving dispersion of pearlite, eliminating internal stress, preventing decarburization and adopting slow cooling rate can obtain spherical pearlite |
For hyper-eutectoid steel | Intermediate heat treatment, finished pipe heat treatment and spheroidizing heat treatment |
| Recrystallization annealing |
Ac1 From 600 to 700℃ |
Eliminating internal stress and work hardening, reducing hardness and restoring plasticity
|
All kinds of carbon steel and low alloy steel | Intermediate heat treatment |
| Normalizing |
Above Ac3 From 30 to 50℃ |
Improving the machinability of mild steel and mechanical properties, refining austenite grains and eliminating net carbide |
Hyposteel | Finished pipe heat treatment |
| Quenching | Eliminating work hardening and internal stress | Intermediate heat treatment and finished pipe heat treatment for stainless steel pipes | ||
| Quenching and high temperature tempering | Normalizing and high temperature tempering and annealing and tempering | Eliminating internal stress, improving toughness of the material and obtaining high strength and hardness | Low alloy structural steel |
Finished pipe heat treatment |
Difference Between Hot Rolled Steel And Cold Rolled Steel Pipe
- Hot-rolled steel and cold-rolled steel have different causes of residual stress, so the distribution on the section is also very different
- The free torsional stiffness of hot-rolled steel is higher than that of cold-rolled steel, so the torsion resistance of hot-rolled steel is better than that of cold-rolled steel.

Advantages of cold rolled seamless pipe
- cold rolling can cause large plastic deformation of steel
- high output

Disadvantages of Carbon Steel Cold Rolled Pipe
- Residual stress caused by uneven cooling
- Residual stress is the internal self-balanced stress without external force
- Hot-rolled steel sections of various cross-sections have such residual stresses
