WE SUPPLY GENERAL STEEL PRODUCTS FOR A WIDE RANGE OF CONSTRUCTION PROJECTS

Stainless Steel (Stainless Steel) is defined in GB/T20878-2007 as a steel with stainless steel and corrosion resistance as its main characteristics, with a chromium content of at least 10.5% and a carbon content of no more than 1.2%. 

Stainless steel is the abbreviation of stainless and acid-resistant steel. 

The steel that is resistant to weak corrosive media such as air, steam and water or has stainless steel is called stainless steel; 

Corroded steel is called acid-resistant steel. Due to the difference in chemical composition of the two, their corrosion resistance is different. 

Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. 

The term "stainless steel" does not simply refer to one type of stainless steel, but to more than one hundred industrial stainless steels, each developed to perform well in its specific field of application.

The key to success is to first understand the application and then determine the correct steel grade. 

There are usually only six steel grades associated with building construction applications. 

They all contain 17-22% chromium, and the better grades also contain nickel. 

The addition of molybdenum can further improve atmospheric corrosion, especially corrosion resistance to chloride-containing atmospheres. 

Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.
