Stainless steel containers are made of stainless steel. Stainless steel is the universal name for a number of different steels used primarily for their anti-corrosive element. This steel has been developed to resist a number of corrosive environments. It ensures that our workplaces are safe, that buildings last longer and that our food preparation surfaces are hygienic. It is also an earth friendly material; it can be melted down, recycled and made into something else.
Stainless steel is always made using chromium. The minimum amount of chromium used is 10.5%; it is chromium that makes the steel stainless. Chromium also improves the corrosion resistance by forming a chromium oxide film on the steel. This very thin layer, when placed under the right conditions, can also be self-repairing.
There are other elements used to make this steel as well, including nickel, nitrogen and molybdenum. Bringing these elements together forms different crystal structures that enable a variety of properties in machining, welding and forming.
There are four major types of stainless steel. Of these, austenitic is the most widely used type. It has a nickel content of at least 7%, which makes it very flexible. Ferritic stainless steel has similar properties to mild steel, but better corrosion resistance. Martensitic stainless steel is a very hard, strong steel. There is also a duplex steel that is a composite of austenitic and ferritic steels. This steel is both strong and flexible.
Stainless steel is a very versatile material. It can literally be used for years and remain stainless. Products made from it have a significantly longer lifespan than products made of other materials. The maintenance costs are lower, and stainless steel also has a very high scrap value.
Therefore, the stainless steel container than the average container corrosion resistance, has longer life, and low maintenance costs.More:http://www.zonghuanmachinery.com
