The Characteristics of Stainless Steel

Introduction to stainless steel

In Taiwan, stainless steel is commonly called white iron due to its white surface appearance and resistance to rust. It can be seen in our daily life, such as stainless steel cleaning kits, trolleys, sinks, racks, etc.Different types of stainless steels have different corrosion resistance, ductility, magnetism and workability features.


Stainless steel does not rust the secret

In normal air conditions, stainless steel is more resistant to rust than carbon steel. Stainless steel is not easy to rust due to the composition of chromium that would form a protective layer of chromium oxide of thickness about 10~50A (1A = 8-10u). This prevents direct contact with the air to resist corrosion. Stainless steel is an alloy composing of iron, chromium, carbon and many other elements. Therein, iron is the main constitution, followed by chromium. In stainless steel, the chromium content must at least be 11%; if not, it cannot form a protective film to resist rust, and if yes, it will resist rust.


The so called stainless steel #304 is composed of 18% chromium and 8% nickel, with the characteristics of non-magnetic, cannot be heat treated, and has good workability. The other category #430 is composed of 16~18% chromium with a low carbon content, and has a magnetic feature to attract ferrous objects. Stainless steel with no nickel content is cheaper and widely used in kitchen utensils, woven nets, decorations, etc. Stainless steel products are 100% recyclable and still have a remaining value even if they are used until the end of lifespan.


YJ Stainless,Quality Assurance

Rust-resistant #304 stainless steel materials are principally used by YJ Stainless Steel Co., Ltd. The company’s products are provided with one year warranty (under the conditions that the damages are not caused by misuse or vandalism), and a material certification (supplied by the original manufacturer). With its own factory in Taiwan, YJ produces and markets products all by itself to ensure quality, allowing Custom-made stainless steel products to use them with ease.
