When comparing corrosion resistance, Stainless Steel generally outperforms aluminum in most environments. The chromium content in Stainless Steel forms a passive oxide layer that protects against rust and corrosion. While aluminum naturally develops an oxide layer, Stainless Steel offers superior protection, especially in chloride-rich environments like coastal areas. The corrosion resistance of Stainless Steel can be further enhanced by increasing chromium content or adding elements like molybdenum.

Stainless steel pipes are widely favored for their exceptional corrosion resistance. These pipes contain at least 10.5% chromium, which forms a dense chromium oxide protective film on the surface, effectively resisting erosion from water, air, and various chemicals. Among them, 304 and 316 stainless steel pipes exhibit outstanding corrosion resistance, with 316 stainless steel pipes offering superior resistance to chloride corrosion due to the addition of molybdenum.

The production process of stainless steel coils mainly includes hot rolling, cold rolling, annealing, acid washing, and finishing. Firstly, stainless steel coils are heated to high temperatures through hot rolling process and then rolled into thicker coils. Subsequently, the cold rolling process further rolls the stainless steel coil to make its thickness thinner and surface smoother.

The specifications of stainless steel bars mainly include four categories: diameter, length, material, and surface condition. Common diameters range from 1mm for small sizes to 300mm for large-diameter bars, with standard lengths typically being 3-6 meters in fixed or random sizes. Among various materials, 304 and 316 stainless steel bars are the most widely used, with 316 stainless steel bars offering better corrosion resistance due to their molybdenum content.
