Features of hot rolled steel tube:

1. The material is uniform, and the cold-drawn or normalized state has lower hardness and higher strength than the annealed state.

2. Good processing performance: It is generally used to manufacture parts with high dimensional accuracy and complex shapes,

which not only improves work efficiency but also saves materials and processing costs.

3. Good weldability: various forming techniques (crimping, bending, etc.) are acceptable.

4. After heat treatment, a relatively uniform residual stress layer can be obtained, which is beneficial to subsequent mechanical processing;

5. High hardenability (up to 60-100mm), good plasticity when hardened in oil;

6. No temper brittleness;

7. Good corrosion resistance and oxidation resistance at low temperatures.
