Stainless Steel
Stainless Steel (Stainless Steel) according to GB/T20878-2007 is defined as stainless steel, corrosion resistance as the main characteristics, and the chromium content is at least 10.5%, carbon content is not more than 1.2% steel. Stainless steel is short for stainless acid-resistant steel, resistant to air, steam, water and other weak corrosion media or with stainless steel called stainless steel; And the chemical corrosion medium (acid, alkali, salt and other chemical erosion) corrosion of steel called acid resistant steel.
Application
|
Construction
|
Stainless steel is widely used in the construction field, such as the production of access control, railing, stair railing, wall decoration, roof plate and other building parts. It has excellent corrosion resistance and can be used in harsh climate environment for a long time. At the same time, it can also be treated by gloss and so on to give it a beautiful appearance.
|
|
Automotive field
|
Stainless steel is also one of the materials widely used in the automotive industry. Its high temperature resistance and corrosion resistance make it an ideal material for making exhaust pipes, diesel fuel tanks, brake systems, wheels and other automotive components. In addition, stainless steel mesh, stainless steel tube can also be used for automotive parts screening and filtration
|
|
Medical devices
|
Stainless steel has good biocompatibility and corrosion resistance, so it is often used to make surgical instruments, dental equipment, artificial joints, etc. Its resistance to corrosion has also made stainless steel an indispensable ingredient in the production of pharmaceuticals and cosmetics.
|
|
Food processing
|
Stainless steel is also one of the common materials in the food processing industry. Because the safety and quality of food is related to people's health, stainless steel has good corrosion resistance, easy cleaning, will not produce any pollution to food, so it is widely used in the production of food processing equipment, kitchen appliances, etc.
