At Namo Alloy, we supply a vast range of Stainless Steel 304 and 304L Sheets, Plates, and Coils tailored for precision engineering. Known for their exceptional formability and weldability, these sheets are the industry standard for kitchenware, chemical containers, and architectural paneling. Our stock includes various surface treatments from Hot Rolled (No. 1) for industrial strength to Cold Rolled (2B, BA) and decorative finishes like No. 4 (Brushed) and 8K (Mirror). The 304L low-carbon chemistry ensures that our plates remain durable and corrosion-resistant even after heavy welding. All our flat products are 100% mill-certified to ASTM A240 standards, ensuring consistent thickness and superior flatness.
