321 Stainless Steel Strip
321 stainless steel strip belongs to the Ni-Cr-Mo austenitic stainless steel family and shares a close resemblance in performance with 304 stainless steel strip.
However, its superior resistance to grain boundary corrosion and high temperature strength can be attributed to the addition of titanium alloy content. This addition effectively regulates the formation of chromium carbide.
321 austenitic stainless steel strip exhibits excellent corrosion resistance in atmospheric conditions and finds extensive applications in industries such as petrochemical, electric power, bridge construction, and automobile manufacturing.

Features of 321 stainless steel strip
The features of 321 stainless steel strip include:
Corrosion Resistance: 321 stainless steel strip offers excellent corrosion resistance, particularly in high-temperature environments. It exhibits superior resistance to intergranular corrosion, making it suitable for applications where exposure to corrosive chemicals and elevated temperatures is expected.
High Temperature Strength: Due to its alloy composition, including the addition of titanium, 321 stainless steel strip possesses enhanced strength and stability at high temperatures. It can withstand prolonged exposure to elevated temperatures without significant loss in mechanical properties.
Grain Boundary Corrosion Resistance: The titanium content in 321 stainless steel strip helps prevent the formation of chromium carbides at grain boundaries, which can cause sensitization and subsequent intergranular corrosion. This feature enhances its resistance to grain boundary corrosion, making it suitable for applications involving welding or prolonged exposure to high temperatures.
Excellent Formability: 321 stainless steel strip demonstrates good formability, allowing it to be easily shaped, bent, or fabricated into various components or structures. It can undergo processes such as cold working, deep drawing, and machining without compromising its properties.
Versatile Applications: 321 stainless steel strip finds application in a wide range of industries. It is commonly used in aerospace components, exhaust systems, heat exchangers, chemical processing equipment, and other high-temperature and corrosive environments where its unique combination of properties is advantageous.
It’s important to note that while 321 stainless steel strip offers several favorable features, specific performance and characteristics may vary depending on factors such as the manufacturing process, surface finish, and specific application requirements.
