The main components of 304 stainless steel cold rolled coil include more than 18% chromium and more than 9% nickel, which makes it have good corrosion resistance and heat resistance. It has excellent high temperature resistance and a wide range of operating temperatures, from -196°C to 800°C.
In addition, 304 stainless steel annealed coil is easy to stamp and bend, and there is no heat treatment hardening phenomenon. The hardness and strength are higher than hot rolled coils, and the ductility is slightly weaker, which is suitable for deep processing (stamping, bending).
304 stainless steel cold rolled coil has a wide range of applications, including food production equipment, chemical equipment, medical equipment, architectural decoration, etc.
