stainless steel 304 - coil slitting 304 UNS S30400 With its chromium-nickel content and low
carbon, Type 304 is the most versatile and widely
used of the austenitic stainless steels. Occasionally
referred to as “18-8,” it has better
corrosion resistance than Type 301 or 302 and offers
excellent drawing and forming characteristics. It
offers satisfactory service at high temperatures
although carbide precipitation may occur with prolonged
exposure to the temperature range of 800°-1600°F.
This “all-purpose” grade has many applications,
including atomic reactor equipment, chemical processing
equipment, food processing equipment, pharmaceutical
equipment and general industrial applications.
