T1 and T2 aluminized steel Part II
So can T1 replace T2? Is this scientific? Next we will analyze three aspects of metal protection:
1. Weather resistance: Strictly speaking, aluminum forms alumina during the oxidation process, and silicon forms silicon oxide. The stability of alumina is slightly better than silicon oxide, but if you want to destroy the chemical bond between the two, the temperature should be at least above 1700 and 2050 degrees Celsius.
Therefore, in general application scenarios, there is no obvious difference in weather resistance between the two, because the energy required to destroy Al-O and Si-O is too great! If you have to make a comparison, T1 is slightly weaker than T2 in this aspect.
2. Chemical resistance: Because aluminum is an active metal and silicon is a non-metal, aluminized silicon steel plates have better chemical resistance than pure aluminum coating in acidic and alkaline environments. Therefore, in this aspect , T1 is obviously better than T2!
3. Mechanical resistance: Because of the presence of silicon, the aluminum-silicon coating not only does not form a rich Fe-Al hardened layer on the surface of the steel base, which makes the aluminum-silicon steel plate have better processability, but also makes the alloy coating slightly harder than pure aluminum coating, so in this aspect, T1 is obviously better than T2!
