As the basis of stainless steel pipes iron, Nickel and chromium. Increases the corrosion resistance of the material of the additional protective coating: Nickel plating, chrome plating, zinc plating, litrovaya. Also increases the corrosion resistance of the passivation with the help of special solutions, which form a protective oxide film on the surface. .
The basic percentage of chromium (at least 10.5 per cent). To improve the corrosion resistance are added such elements as molybdenum, vanadium, Nickel, zirconium.
Mechanical properties (t° 20°C)
sin the Limit of short-term strength 450−900 MPa
sT — the Limit of proportionality (yield strength for permanent deformation) 200−650 MPa
d5 — elongation at break 10−39%
Evaluation of corrosion resistance of metals
The corrosion resistance of the material is evaluated in points If the corrosion rate from 0.01 to 0.1 mm/year (4−5 points), the material is resistant to corrosion. From 0.001 to 0.005 mm/year is highly persistent. And less than 0.001 mm/year is absolutely stable. The latter group includes gold, pure titanium and titanium alloys.
