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.

|17-4 PH||Precipitation hardened, can be heat treated to high levels of hardness and strength. Features machinability and corrosion resistance.|
|201||Lower and more stable cost due to the substitution of lower cost manganese and nitrogen. This is a less expensive option, with good resistance to corrosion and tarnishing.|
|303||Corrosion resistant to sterilizing solutions, most organic and inorganic chemicals, most dyes, nitric acid, and atmospheric exposures.|
|304||Offers resistance to corrosion, has good formability and can be readily welded by all methods. One of the most commonly used grades across the industry.|
|304L||Extra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.|
|309||Used for high temperature and high scale resistance applications. Corrosion resistance is superior to that of 304. Resists corrosion on welded parts.|
|316||Better 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.|
|316L||Extra 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.|
|321||Stabilized using titanium for weldments subject to harsh corrosion. No carbide precipitation and immune to organic and inorganic chemicals.|
|409||Lowest cost in terms of stainless. Used in automotive exhaust systems. Its resistance to oxidation and corrosion is good, the finish or look does not matter.|
|416||Good corrosion resistance. Additional sulfur in its chemistry makes 416 easier to machine.|
|430||Most popular of the non-hardenable stainless steels. Has great corrosion and heat resistance with good mechanical properties.|
|440 F-Se||One of the hardest stainless steels. The extra carbon allows for a long lasting sharp edge when heat treated properly.|
