What are the main types of Shenyang 40Cr round steel?
Edit:Shenyang Sidi Ou Trading Co., Ltd.   UpDate:2018-05-29

Stainless steel not only refers to a type of stainless steel, but also represents more than 100 industrial stainless steels, each of which has good properties in its specific application area. The key to the success of the main types of Shenyang 40Cr round steel is to clarify the use and then determine the correct steel. Usually only six types of steel are associated with the application of the building. They all contain 17 22 chrome, and a good fraction contains nickel. The addition of molybdenum can further improve the corrosiveness of the atmosphere, especially the corrosion resistance of the chloride environment.

Ferritic stainless steel: Numbers containing chromium. As the chromium content increases, its corrosion resistance, toughness and weldability increase, and the corrosion resistance of chloride is superior to that of other types of Shenyang 40Cr round steel . Due to its high chromium content, ferritic stainless steel has good corrosion and oxidation resistance, but its mechanical properties and process performance are poor. It is more suitable for the use of acid-resistant structure and anti-oxidation steel.

Austenitic stainless steel: This steel has good plasticity, toughness, weldability, corrosion resistance and non-magnetic or weak magnetic properties. It has good corrosion resistance in oxidizing and reducing media, and is used in acid-making equipment such as corrosion-resistant containers and Equipment lining, transfer lines, nitric acid corrosion resistant equipment, etc.

Austenitic-ferritic duplex stainless steel: This type of Xi'an stainless steel has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and intergranular corrosion resistance. Both the properties and the weldability are significantly improved, while maintaining the brittleness and high thermal conductivity of the ferritic stainless steel 475, which has superplastic properties.

What are the main types of Xi'an stainless steel?

Precipitation hardening Shenyang 40Cr round steel : The matrix is ​​austenitic or martensitic, precipitation hardened stainless steel. It can be treated with precipitation hardening (also known as age hardening) to make it hard (strong) stainless steel.
