304/304L Stainless Steel

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 slightly lower strength than 302 due to its lower carbon content. Type 304 finds extensive use in welding applications because the low carbon permits some exposure in the carbide precipitation range of 800°F - 1500°F without the need for post-annealing operations. However, the severity of corrosive environments may necessitate annealing after welding or the use of 304L.

Type 304L has a carbon content of 0.03% or less. This alloy can be used in the as-welded condition without becoming susceptible to intergranular corrosion.

316/316L Stainless Steel

Type 316 is a molybdenum steel possessing improved resistance to pitting by solutions containing chlorides and other halides.

In addition, it provides excellent elevated temperature tensile, creep and stress-rupture strengths.

310S Stainless Steel

310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.

Cyclic conditions reduce its oxidation resistance, and a maximum operating temperature of 1900°F is generally recommended if cycling is involved.

Having a lower coefficient of expansion than most 300 stainless steels, 310S may be used in operations involving moderately severe thermal cycling, such as rapid air cooling. It is not usually recommended for liquid quenching. Although 310S has less resistance to absorption of carbon and nitrogen than the higher alloys such as 330 and 333, it is widely used in moderately carburizing atmospheres such as encountered in petro-chem plants.

Because of ts high chromium and medium nickel contents, 310S may be used in atmospheres containng moderate amounts of sulfur.

317L Stainless Steel

317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.

It has a supperior corrosion resistance in special applications where it is desired to reduce contamination to a minimum. 317L was developed primarily to resist more effectively the attack of sulfurous acid compounds. Howerver, its proven ability to combat corrosion has widened its use considerably and is now being used for many other industrial applications.

The low carbon content of 317L provides immunity to intergranular corrosion in applications where heavy cross sections cannot be annealed after welding or where low temperature stress relieving treatments are desired.

321/321H Stainless Steel

Type 321 is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents.

These titanium bearing stainless steels are stabilized against carbide precipitation and designed for eperation within the damaging temperature range where carbide precipitation develops. In this type of steel, the carbon combines preferentially with titanium to form a harmless titanium carbide, leaving the chromium in solution ot maintain full corrosion resistance.

Duplex 2205 (UNS S31803)

Duplex 2205, or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.

The high amounts of molybdenum and chromium content in 2205 offer strength, improved pitting and consistent stress corrosion cracking resistance. 2205 integrates the best features of austenitic and ferritic steels (as well as nearly equal amounts of austenite and ferrite) and can be welded with common stainless steel welding techniques – its uniform composition minimizes localized corrosion.
