Description:304 stainless is a low-carbon (0.08% max)version of basic 18-8, also known as 302.Type 302 has 18% chromium and 8% nickel.

Type 304 has a slightly lower strength than302 due to its lower carbon content. Type 304is used in welding applications, because thelow carbon permits some exposure in thecarbide precipitation range of 800° F - 1500°F without the need for post-annealingoperations. However, the severity of thecorrosive environments may necessitateannealing after welding or the use of 304L.Type 304L has a carbon content of 0.03% orless.

Typical Applications:

• Sanitary systems• Dairy and food processing• Heat exchangers, evaporators

• Feedwater heaters

Description: Alloy 310S has excellent resistance tooxidation under constant temperatures up to2000° F. Cyclic conditions reduce its oxidationresistance, and a maximum operatingtemperature of 1900° F is generallyrecommended if cycling is involved. Having alower coefficient of expansion than most 300stainless steels, 310S may be used inoperations involving moderately severthermal cycling, such as rapid air cooling. Itsnot usually recommended for liquid

quenching. 310S is widely used inmoderately carburizing atmospheres such aspetro-chemical plants.

Description:These titanium-bearing stainless steels arestabilized against carbide precipitation. Theyare designed for operation within thedamaging temperature range where carbideprecipitation develops. In this type of steel,the carbon combines preferentially withtitanium to form a harmless titanium carbide,leaving the chromium in solution to maintainfull corrosion resistance. Type 321 is basictype 304 modified by adding titanium in anamount at least 5 times the carbon-plus-nitrogen contents.

Description: Avesta Sheffield 2205 is a ferritic-austeniticstainless steel which combines many of thebeneficial properties of both ferritic andaustenitic steels. As a result of high chromiumand molybdenum contents, the steel has verygood pitting and uniform corrosion resistance,as well as high mechanical strength. 2205 hasgood weldability and can be welded usingmost of the techniques for stainless steels.Due to the balanced composition, when

welded correctly, the heat-affected zonecontains sufficient austenite to avoid risk oflocalized corrosion.

Typical Applications:• Heat exchangers, tube & pipe for gas & oil• Heat exchangers and pipes in desalination plants• Pressure vessels, pipes, & tanks for various chemicals and chlorides• Rotors, fans, shafts and press rolls where high corrosion fatigue is needed

Description:254SMO is an austenitic steel designed for

maximum resistance to pitting and crevicecorrosion. With high levels of chromium,molybdenum and nitrogen, 254SMO isespecially suited for high chlorideenvironments such as brackish water,seawater, pulp mill bleach plants and otherhigh-chloride process streams. In newconstruction, 254SMO has been found inmany cases to be technically adequate andmuch less costly substitute for nickel-basedalloys and titanium. 254SMO is readilyfabricated and welded.

Description:P91 is basic P9 modified by the addition of

small amounts of vanadium andcolumium/niobium, which greatly improvesthe creep strength and allows operation athigher pressure and temperature. P91 givesmore flexibility and cost savings than P22 byreducing the wall thickness thanks to theimproved creep properties and resistanceagainst high-pressure hydrogen. P91 ispreferred over P22 and P5 in sulfur-richatmosphere furnaces
