Al Shakru Sheets and Plates, based in Dubai, UAE, distinguishes itself as a leading manufacturer and supplier of Stainless Steel 321 Coils and Slitting Coils . They are renowned for their remarkable corrosion resistance, high-temperature stability, and overall durability. Made from titanium-stabilized austenitic stainless steel, these coils are engineered to prevent carbide precipitation and intergranular corrosion, guaranteeing outstanding performance in high-temperature environments. Al Shakru Sheets and Plates takes pride in precise manufacturing and strict quality control, supplying 321 coils that comply with international standards. These coils are ideal for a wide range of applications across industries such as chemical processing, power generation, and beyond, offering dependable performance, structural integrity, and resistance to scaling and oxidation even under the harshest conditions.
Stainless Steel 321 Coils and Slitting Coils consist of chromium (17–19%), nickel (9–13%), and titanium, which enhances their resistance to high-temperature corrosion and works to avoid sensitization. They feature a tensile strength of roughly 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. Having a density of 8.0 g/cm³ and a melting range of 1390–1425°C, these coils deliver outstanding toughness, formability, and weldability, guaranteeing that they stay mechanically stable and dependable over time, even within corrosive and high-temperature settings.
