Known for their precision engineering and commitment to international standards, Lecong Stainless guarantees that every coil delivers reliable performance and durability. Thanks to their cutting-edge facilities and a talented workforce, they produce coils that meet the strict demands of various industries. With a strong focus on excellence, the company blends advanced manufacturing techniques with thorough quality control, resulting in Stainless Steel 321 Coils that are not only corrosion-resistant but also built to last, catering to a wide range of industrial needs.
Stainless Steel 321 Coils are made up of about 17–19% chromium, 9–12% nickel, and 0.08% carbon, with titanium added to stabilize the structure and prevent carbide precipitation. This unique blend boosts their resistance to intergranular corrosion, especially after being exposed to high temperatures. On the mechanical side, these coils boast impressive tensile strength, yield strength, and ductility, making them perfect for forming and welding processes. They hold up well under extreme thermal conditions, resisting scaling and oxidation, and they have good toughness, ensuring dependable performance in high-stress situations.
