Introduction to pure titanium TA0

X12Cr13 is a stainless steel with a mainly ferrite structure and a chromium content between 11% and 30%. It has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance and excellent stress corrosion resistance. It is mostly used to manufacture parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion.

Stainless steel is widely used in the automobile transportation industry due to its high strength, relatively lightweight, good energy absorption and safety properties. The exhaust pipe part of each car usually uses 40~50kg of ferritic stainless steel. This kind of stainless steel generally does not contain nickel, and sometimes contains small amounts of Mo, Ti, Nb and other elements to further improve its performance.

However, this type of steel has shortcomings such as poor plasticity and significantly reduced plasticity and corrosion resistance after welding, so it is limited in some applications. Through out-of-furnace refining technology (such as AOD or VOD), the content of interstitial elements such as carbon and nitrogen can be reduced, thereby improving the performance and application range of this type of steel.

In general, X12Cr13 stainless steel is widely used in manufacturing parts in corrosion-resistant environments due to its corrosion resistance, thermal conductivity and stress corrosion resistance. And in the automotive transportation industry, stainless steel is widely used because of its high strength, lightweight and good safety properties.
