Stainless steel is a type of steel that contains chromium, which gives it excellent resistance to rust and corrosion. It is widely used across various industries such as construction, automotive, and aerospace, thanks to its strength, longevity, and attractive appearance. Below is a brief overview of different stainless steel components, including pipes, tubes, flanges, fasteners, fittings, and round bars.
