When it comes to manufacturing Stainless Steel 321 Coils, Ed Stainless uses austenitic stainless steel that’s stabilized with titanium, which effectively prevents carbide precipitation during welding. The typical chemical makeup includes Chromium (17–19%), Nickel (9–12%), and enough Titanium to stabilize the material. These coils boast impressive mechanical properties, featuring a tensile strength of about 75 ksi (515 MPa), a yield strength of 30 ksi (205 MPa), and an elongation of roughly 40%. Renowned for their exceptional resistance to intergranular corrosion and high-temperature performance, these coils comply with ASTM A240 standards, ensuring reliability and structural integrity even in the toughest environments.
