Brief of 304 304L 304H Stainless Steel Sheet Plate
Background
Grade 304 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. 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.
Grade 304L, the low carbon version of 304, does not require
post-weld annealing and so is extensively used in heavy gauge
components (over about 6mm).
Grade 304H with its higher carbon content finds application at
elevated temperatures.
Key Properties
These properties are specified for flat rolled product (plate,
sheet and coil) in ASTM A240/A240M. Similar but not necessarily
identical properties are specified for other products such as pipe
and bar in their respective specifications
