Stainless steel faucet manufacturer explains why it trusts
When brown rust spots (spots) appear on the surface of sustainless steel pipes, people are greatly surprised: they think that "sustainless steel does not trust, trust is not sustainless steel, it may be a problem with the steel quality" Many customers buying a house is not easy, and decorating it well is even more complicated Did the stainless steel faucet rust and buy a fake?
Stainless steel ≠ never trusts
The rust resistance and corrosion resistance of stainless steel are due to the composition of a chromium rich oxide film (passivation film) on its surface And this trust resistance and conflict resistance are related Simply put, sustainless steel is not simply rusty steel, not non rusty steel! Experiences have shown that the corrosion resistance of steel in weak media such as atmosphere and water, as well as in oxidizing media such as nitrate acid, improves with the increase of chromium content in the steel When the chromium content reaches a certain percentage, the corrosion resistance of the steel gradually changes, from being easy to trust to not easy to trust, and from not being resistant to corrosion
Why does stainless steel also rust?
Stainless steel has the ability to resist atmospheric oxidation - that is, trust resistance, as well as the ability to corrode in media containing acids, alkalis, and salts - that is, corrosion resistance How, its ability to resist corrosion depends on the chemical composition, additive state, service conditions, and type of environmental medium of the steel itself For example, 304 steel pipes have excellent trust resistance in dry and clean atmospheres, but when moved to coastal areas, they quickly trust in sea miss containing a large amount of salt; And 316 steel pipe performs well Theoretical, not any type of stainless steel can be with stand corrosion and trust in any environment
