What is Stainless
Plate?
Stainless plate refers to stainless
steel that has been rolled or forged into a plate of
varying thicknesses. Sandmeyer Steel Company has the
largest single inventory of stainless plates in North
America. This inventory includes austenitic, martensitic,
duplex, and precipitation hardened types.
Below are a few examples
of the stainless plate grades available at Sandmeyer
Steel Company:
304 Stainless
Steel Plate
304, 304H, and 304L stainless plates are an austenitic
stainless steel, a basic alloy containing minimum chromium
(18%) and nickel (8%) and maximum carbon (.08%). The
304H and 304L types vary these amounts. The 304 stainless
plates are available in 3/16" through 6-1/2"
at 1/8" increments. With high levels of corrosion
resistances, alloy 304 avoids product contamination,
has an aesthetic appearance, and is easily cleaned,
formed, and fabricated.
316 and
316L Plate
316 stainless plate and 316L stainless plate are molybdenum-bearing
austenite with varying levels of resistance to corrosion,
pitting, and crevice corrosion. Available in thickness
from 3/16” to 6-1/2” in 1/8” increments,
316 and 316L stainless plate also comes as E-Z drill
for better machinability. 316 and 316L stainless plates
can be easily formed and fabricated and have high creep,
stress-to-rupture, and tensile strengths ideal for elevated
temperatures and severe environments.
347 Stainless
Plate
Offered in thicknesses ranging from 3/16” through
3”, 347 stainless plate is made of stabilized
stainless steel containing niobium (columbium) and tantalum.
With higher creep and stress rupture properties, Alloy
347 has good mechanical properties and resists intergranular
corrosion even after extensive time in elevated temperatures.
410 Stainless
Plate
Available in thicknesses from 3/16” to 4”,
410 stainless plate is a martensitic grade stainless
steel which is hardenable and useful for many applications.
In addition to excellent corrosion and wear resistance,
410 stainless plate has high strength after being oil
quenched between 1700°F to 1850°F (927-1010°C).
17-4PH Stainless
Plate
17-4PH is a martensitic, precipitation-hardened stainless
steel and combines high strength and hardness with corrosion
resistance. Alloy 17-4PH has the highest corrosion resistance
out of all hardenable stainless steels and additionally
has a higher yield strength, attaining 1130 –
1300 MPa (160-190 ksi) after heat treatment. Sandmeyer
Steel Company stocks annealed 17-4PH stainless plate
in thicknesses ranging from 3/16” to 3”.
Sandmeyer Steel Company is pleased to offer a large
inventory of duplex stainless plates, including 2205
and 2507 .
