Stainless steel is a rust-resistant alloy containing iron and at least 10.5% chromium, and consisting of nickel or molybdenum, which forms a protective layer of oxidation that prevents rusting and staining. With a hygienic, easy-to-clean surface and heat resistance, this versatile material is used in a wide range of applications including cookware, medical equipment, construction and industry. Stainless steel is available in various grades, such as 304 and 316, and the material is recyclable, durable and requires minimal maintenance.
