Chemical Requirements

Mechanical Properties of Small-Diameter and Light-Wall Tubing

Delivery Conditions :

1. Annealed - Soft,with a dull matte finish

2. Stress Relieved - Thermally treated below the annealing tempreature to relieve the major portion of the internal stress, with a thin , light to medium-dark surface

Characteristics:

1. Good mechanical properties

2. Yield tensile strength

3.Highly resistant to chloride and sulfide stress corrosion cracking

4. Resistant to aqueous corrosion and chloride ion stress corrosion cracking

5. High temperature resistant

6. Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.

7. Excellent welding characteristics
