Corrosion of metals and alloys
This section contains general information about rolled metal products and corrosion protection measures. The corrosion resistance of metals and alloys is evaluated by the value of losses from 1 square meter of surface.
| Corrosion resistance | loss weight per 1 sq. meter. | Rating in points |
|---|---|---|
| Extremely resistant metals | Less than 0,001 g | 1 |
| Very persistent metals | 0,001 - 0,005 | 2 |
| 0,005 - 0,01 г | 3 | |
| Persistent metals | 0,01 - 0,05 г | 4 |
| 0,05 - 0,1 г | 5 | |
| Satisfactorily resistant metals | 0,1 - 0,3 г | 6 |
| Poorly resistant metal | 0,3 - 1,0 г | 7 |
| 1 - 5,0 г | 8 | |
| Unstable metal | More than 5 g. | 9 |
Comparative tests of corrosion resistance in industrial and marine atmospheres revealed that aluminum alloys, stainless steels, copper-nickel alloys and Inconel alloy showed visible signs of corrosion over a five-year period, while the titanium plate did not lose its original luster. This corrosion resistance is due to the presence of a passive oxide film on the surface of titanium, which protects the metal from contact with an aggressive agent.

We also offer optimum conditions for retail customers. The high level of service is justly the face of our company.
Corrosion, types
As for the mechanism of the process itself, the specialized literature defines 2 types of corrosion of metals - it is electrochemical and chemical. At the same time, the rate of material destruction can only be determined by experience, as it depends on the nature of the elements formed. Either way, but the process of metal corrosion leads to a loss of functional qualities of the part, followed by the destruction of products made of steel or other alloys

Since almost all metals are subject to corrosion to some degree, it leads to significant economic losses. We are talking not only about direct losses due to destruction of the structure, but also about the associated costs (equipment downtime, violation of production technology, the purchase of protective equipment and much more). Since the essence of metal corrosion is usually reduced to oxidation with the formation of oxides, modern science offers 3 main ways to combat spontaneous destruction: structural, active and passive.
