304 Stainless Steel ASTM F593

This stainless steel is also known as 304 in the American AISI grade designation system or 1.4301 in the European BS EN 10088 standard. This is a basic alloy. It cannot be heat hardened and is also non-magnetic. While this grade of stainless steel won’t rust, it will tarnish and has a strong resistance to the effect of various chemicals and acids. It is commonly used for sinks, pots, pans, tables and similar. As such, 304 stainless steel is very often used in the dairy and brewing industries.

The specification below for ASTM F593 covers the requirements for 304 series stainless steel bolts, hex cap screws, and studs 0.25 to 1.50 in., inclusive, in nominal diameter in a number of alloys in common use and intended for service applications requiring general corrosion resistance.
