ASTM A240 Alloy 321 (UNS S32100) is titanium stabilized austenitic stainless steel plate with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.
ASTM A240 Alloy 321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.
Alloy 321 stainless steel plate cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.
ASTM A240 Stainless Steel, also known as inox steel, is a steel alloy with a minimum of 10.5 or 11% chromium content by mass.
Stainless steel Plate does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof.
The term 'corrosion resistant steel' is used when the alloy has less than the 12% minimum of chromium, for example in the aviation industry. There are different grades and surface finishes of stainless steel, depending on where it will be used. Stainless steels have a higher resistance to oxidation (rust) and corrosion in many natural and man-made environments; however, it is important to select the correct type of stainless steel for the use. There are over 150 grades of stainless steel, of which fifteen are the most used.
