Stainless Steel Flat Bar Grade 304 / 1.4301/06Cr18Ni9 Flat Steel
Bar / SS Flat
304 stainless steel flat bar or “flat stock” is an excellent
candidate for most processing techniques as well as both indoor and
outdoor applications. This product has a semi-smooth, dull grey
finish and sharp defined edges with accurate dimensions throughout
length. 304 stainless steel is a high strength material with
excellent corrosion resistance making it ideal for shelves,
brackets, bracing, sculptures, and other architectural uses. Also
found within the food and beverage industry, aerospace
applications, and chemical processing. ASTM A276-10 is the standard
specification for structural stainless steel.

Stainless Steel Flat bar, is the most economical stainless flat
shape that’s ideal for all applications where strength and superior
corrosion resistance is required. 304 Stainless Flat has a durable
dull, grainy mill finish and is widely used for all types of
fabrication projects that are exposed to the elements. Stainless
Flats 1/2″ thickness and under are sheared and edged, thicker sizes
are a true bar. True bar is available on request for thinner sizes.
Notice: 1/16″ strip flats are sheared from sheet and may have some
curvature or twist.
Specifications: ASTM A276, QQS-763, T304/304L, non-polished finish,
1/8″ to 1/2″ thick is sheared & edged, over 1/2″ thick is True Bar
(squared edge).
AKA: stainless strip, stainless bar, stainless rectangle
Applications: frame work, braces, supports, plates, marine, food,
etc.
Workability: Easy to Weld, Moderate Cutting, Forming and Machining.
Mechanical Properties: Brinell = 170, Tensile = 85,000 +/-,
Yield = 34,000 +/-, Nonmagnetic
How is it Measured? Thickness (A) X Width (B) X Length
Available Stock Sizes: 2ft, 4ft, 6ft, 8ft, 12ft, or Cut to Size
