We offer SS 321 Perforated Sheet, Stainless Steel 321 Sheets, UNS S32100 Sheets, and AISI 321 SS CR Sheets, known for their excellent strength and corrosion resistance.
321 is a stainless steel plate that boasts superior corrosion resistance as an alloy steel and is commonly used in many industrial applications.It is essentially formed with iron, chromium, and nickel, along with relatively small amounts of titanium to enhance oxidation and corrosion resistance at elevated temperatures. The main advantage of 321 stainless steel is that it will not lose its strength or durability when conditioned in extreme conditions. For this reason, it is a preferred material in the high-temperature environment of chemical processing plants, power generation, or aerospace industries. Nandini Steel is a leading 321 stainless steel plate supplier, ensuring you get the best for your needs. Our plates are engineered to offer superior corrosion oxidation and scaling resistance, especially in high-temperature settings.As a trusted manufacturer and supplier we pride ourselves on products made to the highest industry standards.
Nandini Steel offers premium 321 Stainless Steel Sheet, 321 Stainless Sheet, and is a reliable 321 Stainless Steel Supplier. We also provide 321 Stainless Steel 2B Finish Sheets for diverse industrial needs.
Features of 321 Stainless Steel Plate
- Superb High-Temperature Strength: In contrast to other grades of stainless steel, 321 Stainless Steel Plate has superior oxidation and scaling resistance at high temperatures, which is suitable for applications involving high heat such as furnace components, boilers and heat exchangers.
- Better Corrosion Resistance: The inclusion of titanium in ASTM A240 Stainless Steel 321 Plate increases its corrosion resistance against intergranular corrosion, and hence it is a better choice compared to other grades, including 304 stainless steel, in extreme conditions.
- Improved Weldability: Both 321 Stainless Steel Plate and 904L stainless steel are exceedingly resilient, yet the latter also has enhanced acid corrosion resistance. 904L finds most usage in very acidic environments but 321 continues to be more suited to varying temperature applications or limited acidic condition exposure.
- Ease of Fabrication: The formability of 321 stainless steel is very good, which enables easy fabrication without sacrificing its strength. It is best for applications that need precise shaping.
Compositions and Properties of 321 Stainless Steel Plate
The composition of UNS S32100 Plates sets it apart from other stainless steel grades. With 17-19% chromium, 9-12% nickel, and 0.8-1.5% titanium, it is designed to resist corrosion and oxidation, particularly in high-temperature environments. The addition of titanium stabilizes the structure, reducing the risk of sensitization during welding and enhancing overall weldability. The chromium provides superior corrosion resistance, while the nickel ensures excellent toughness and strength. This balance of elements gives 321 Stainless Steel Plate the ability to perform well in aggressive and high-temperature environments without compromising its structural integrity.
