Nizar Sheetsandplates is a reputable manufacturer and supplier based in Amman, Jordan, specializing in high-quality Stainless Steel 321 Coils and Slitting Coils for a variety of industrial uses. Renowned for their precision processing, exceptional durability, and customer-focused service, the company guarantees that each coil adheres to strict international standards. With state-of-the-art slitting, cutting, and finishing capabilities, Nizar Sheetsandplates provides coils that boast impressive dimensional accuracy, surface quality, and consistent performance. Their dedication to timely deliveries, technical know-how, and competitive pricing has established them as a go-to supplier in the construction, petrochemical, automotive, food processing, and general engineering sectors throughout Jordan and the wider Middle East.
Stainless Steel 321 Coils and Slitting Coils are composed of chromium (17-19%), nickel (9-12%), and titanium (up to 0.7%), which enhances their resistance to high temperatures and intergranular corrosion. The addition of titanium stabilizes the alloy, preventing carbide precipitation during welding. These coils exhibit excellent mechanical properties, with a tensile strength of around 515 MPa, yield strength of 205 MPa, and elongation of approximately 40%. They perform well in elevated temperatures (up to 870°C) and offer excellent resistance to oxidation and corrosion, making them ideal for high-temperature and corrosive environments.
