Stainless

Stainless Steel is an alloy product composed of Iron, Carbon and Chromium. It is known for its resistance to tarnishing, rust, corrosion, and staining when compared to regular steel.

Available Stainless Shapes

Available Stainless Grades

GradeDescription
17-4 PHPrecipitation hardened, can be heat treated to high levels of hardness and strength. Features machinability and corrosion resistance.
201Lower and more stable cost due to the substitution of lower cost manganese and nitrogen. This is a less expensive option still with good resistance to corrosion and tarnishing.
303Corrosion resistant to sterilizing solutions, most organic and inorganic chemicals, most dyes, nitric acid, and atmospheric exposures.
304Among the most commonly used grades across the industry, it offers resistance to corrosion. Has good formability and can be readily welded by all methods.
304LExtra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.
309Used for high temperature and high scale resistance applications. Corrosion resistance is superior to that of 304. Resists corrosion on welded parts.
316Better pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. 316 can be used for valves, marine equipment, pumps, and chemical equipment.
316LExtra low carbon avoids harmful carbide precipitation due to welding. Same excellent corrosion resistance as 316. It exhibits the same high strength, toughness and workability as 304 alloys.
321Stabilized using titanium for weldments subject to harsh corrosion. No carbide precipitation and immune to organic and inorganic chemicals.
409Lowest cost in terms of stainless, used in automotive exhaust systems. It's resistance to oxidation and corrosion is good, the finish or look does not matter.
416Good corrosion resistance, additional sulfur in its chemistry makes 416 easier to machine. Free machining variation of T410 with corrosion resistance to most atmospheres, basic salts, water, and natural food acids.
430Most popular of the non-hardenable stainless steels. Has great corrosion and heat resistance with good mechanical properties.
440 F-SeOne of the hardest stainless steels, the extra carbon allows for a long lasting sharp edge when heat treated properly.
