"Stainless steel" is the general term for stainless steel. It requires at least 10.5% chromium. The chromium content in steel is very important because it will form a thin layer of chromium oxide on the metal surface to prevent metal corrosion and use. We stock a large number of grades to Adapt to projects of all sizes and complexity.Stainless steel is an iron alloy with a chromium content of at least 10.5%. Although grades such as 304 and 430 are popular grades, the term "stainless steel" covers a variety of metals, each of which has added various alloying elements to enhance its special properties, such as enhanced corrosion resistance or strength.Stainless steel has become very popular due to its relatively low cost, beautiful appearance, high corrosion resistance, and low maintainability.
What makes it stainless?
Chromium in stainless steel reacts with oxygen in the air to form a very thin protective chromium oxide layer on the metal surface. This layer is invisible to the naked eye and protects the surface from corrosion. This layer may be damaged by scratching and continuous exposure to corrosive chemicals. However, because this layer is formed by the reaction of chromium and air, if the surface is properly cleaned, the protective chromium oxide layer will Self-healing to continue to protect the surface. steel.
