Stainless Steel Plate

Stainless Steel in Plate form is defined as a steel alloy with a minimum of 11.5% chromium content by mass. Stainless steel does not stain, corrode or rust as easily as ordinary steel (it is"stains less"), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further corrosion.

Common Stainless Steel Plate Grades are 304 , 304L , 316 , 316L , 317 , 317L ( L) grade stainless represents a lower carbon content

Carbon Content for common stainless grades, Straight Grade 304 , 316 , 317, have a carbon max of / .08 L Grade Stainless 304L , 316L , 317L have a carbon max of / .03

Stainless plate thickness varies from 3/16” to 4” . Inquire about thickness’s beyond 4” Common plate widths are 48”, 60”, 72”, 96”, 120” Inquire about widths larger than 120” Common plate lengths are 8’, 10’, 12’, 20’ Inquire about length longer than 20’. Plate is routinely cut to size per order.
