Is 45# steel stainless steel?
45# is not stainless steel, it is high quality carbon structural steel.
Popularly speaking, stainless steel is not easy to rust steel, in fact, part of stainless steel, both rust resistance, but also acid resistance (corrosion resistance). Stainless steel stainless steel and corrosion resistance is on the surface of chromium rich oxide film (film) formation. The rust resistance is relative to that of corrosion resistance.
Steel in air, water and the weak acid medium and oxidizing medium, the corrosion resistance increased with the increase of Cr content in steel, when the chromium content reaches a certain percentage, the steel corrosion resistance mutation from rust to rust, corrosion and corrosion resistance to never.
