"Stainless steel" refers to a group of iron-based alloys that are resistant to corrosion and rust due to the presence of chromium, typically at least 10.5% by weight. Stainless steel is a corrosion-resistant alloy made primarily of iron, chromium (≥10.5%), and often nickel, molybdenum, and other elements.
Aluminized steel is carbon steel coated with an aluminum-silicon alloy. It combines the strength of steel with the corrosion resistance and heat reflectivity of aluminum. Aluminum and steel are bonded in layered or composite materials for structural or engineering purposes.
Mild steel, also known as low carbon steel, contains a low amount of carbon, typically between 0.05% and 0.25%. This low carbon content is the defining characteristic that makes mild steel more ductile, malleable, and weldable compared to higher carbon steels. In addition to iron and carbon, mild steel may also contain small amounts of other elements like manganese, silicon, phosphorus, and sulfur.
Brass is an alloy primarily composed of copper and zinc, while steel is an alloy of iron and carbon, with other elements sometimes added. Brass typically contains 60-70% copper and 30-40% zinc, with variations depending on the desired properties of the brass. Steel, on the other hand, contains a few tenths of a percent of carbon to improve its strength and fracture resistance compared to iron, and often includes other elements like chromium for stainless steel applications.
