Will Sheets and Plates, based in Hamilton, New Zealand, is a renowned manufacturer and supplier of high-quality metal products, specializing in Stainless Steel 321 Coils and Slitting Coils. Known for their exceptional resistance to high temperatures and excellent corrosion resistance, these coils are ideal for applications in industries such as aerospace, chemical processing, and power generation. With a commitment to precision and customer satisfaction, Will Sheets and Plates provides durable, reliable, and cost-effective solutions tailored to meet diverse industrial needs.
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.
