What Is Stainless Steel Bar
Stainless steel bar stock is a metal alloy that contains at least 10.5% chromium and enough nickel to make it hardenable. Stainless steel bar stock has a higher resistance to corrosion than carbon steel bars because of the alloying mixture's higher chromium and nickel content. This makes it less brittle than a carbon steel bar, so it can be used for certain machine parts without breaking as easily under stress from temperature changes or mechanical shock.

Stainless Steel Bar Grades
The 'grade' of a stainless alloy product denotes precisely what its intended application or environmental resistance will be, and this is dictated by both the specific chemical/elemental makeup of the alloy in question, as well as any finishing or treatment process it has undergone after casting.
Stainless steel grading systems are intended to give users an indication of both the subtype of alloy used, and the range of applications a product is therefore suited to. You'll typically see them written as numbers, occasionally numbers and letters, with a few common examples being:
304 stainless steel
Denotes general-purpose austenitic alloy
01
309 stainless steel
Denotes high temperature-suitable stainless steel
02
430 stainless steel
Denotes ferritic stainless steel for use in food-grade applications
03
316/316L stainless steel
Denotes suitability for '316' (chemical) applications, where the 'L' additionally indicates suitability for welding
04
15-5 PH stainless steel
Denotes precipitation-hardened (thus PH) stainless steel for use in valves, fittings and fasteners
05
Types of Stainless Steel Bar
All bars start as round bar stock before being sized and drawn through the coil line to create precise cross-sectional shapes.
Round bar
Round bars can be used to produce a wide range of consumer and commercial products, structural components, and more. The rounded edges are finished to eliminate the risk of sharp edges down the length of the material. We provide round bar stock made from different stainless steel varieties, such as: 303 stainless steel, which responds well to machining and resists corrosion; 304 stainless steel, which is versatile and heat-resistant; and 316 stainless steel, which has a high molybdenum content to withstand corrosion in marine, outdoor, and chemically caustic environments.
Square bar
Square bars are categorized by their size, or the length of one side of its face. Square bars are commonly used as piers and supports in industrial or construction applications, though they can also be used in ornamental fabrications. Square bars are durable, strong, resistant to damage, and versatile.
Hex bar
Hex bars are available in an array of sizes and lengths, and they have a hexagonal cross-section. Size is categorized by the distance from one flat face to the flat face on the opposite side of the steel hex bar, rather than the length of a given face.
Because of the bar's hexagonal shape, it's commonly used to produce volumes of fasteners, such as washers, nuts, and other fittings. The lengths of bar can be cut down to size and then drilled or machined to create threaded openings throughout its length.
Flat bar
Flat stainless steel bars are generally available in two varieties: Edge-treated bars with sheared, cost-effective edges that are then smoothed as the bar is flattened; and the stainless steel flat bars, which are uniformly produced through hot rolling, annealing, and pickling or cold drawing. Edge-treated flat bars are cost effective, while true bars are precise and sharp. Stainless steel flat bars are available in many sizes, thicknesses, and stainless steel alloys.

Stainless steel bar is typically composed of steel which has been produced by alloying numerous metals together with at least 10% of chromium. Chromium can be easily utilized in other shapes or forms. Other than chromium, it is usually composed of differing amounts of nickel, nitrogen, and molybdenum, which affect its properties.
The chromium oxide forms the thin layer on the outside of the steel which is unnoticeable by the naked eye, which is self-healing if scratched and bendable. Its re-healing properties are only active when in touch with the oxygen gas when the steel is in use in a non-oxygenated environment such as underwater, corrosion may happen more easily.

Classes of Stainless Steel Bar
Austenitic: Chromium-nickel-iron alloys with 16-26% chromium, 6-22% nickel (Ni), and low carbon content, with non-magnetic properties (if annealed - working it at low temperatures, then heated and cooled). Nickel increases corrosion resistance. Harden able by cold-working (worked at low temperatures) as well as tempering (heated then cooled). Type 304 (S30400) or "18/8" (18% chromium 8% nickel), is the most commonly used grade or composition.
Martensitic: Chromium-iron alloys with 10.5-17% chromium and carefully controlled carbon content, harden able by quenching (quickly cooled in water or oil) and tempering (heated then cooled). It has magnetic properties. Commonly used in knives. Martensitic grades are strong and hard, but are brittle and difficult to form and weld. =
Ferritic: Chromium-iron alloys with 17-27% chromium and low carbon content, with magnetic properties. Cooking utensils made of this type contain the higher chromium levels. Type 430 is the most commonly used ferritic. Two additional classes worth mentioning include Duplex (with austenitic and ferritic structures), and Precipitation Hardening stainless steel, used in certain extreme conditions.
