Grade ASTM A240 304 Stainless Steel is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. ASTM A240 Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
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.
