Stainless Steel

Type 304

Alloy 304 (UNS S30400) stainless steel is a variation of the 18% chromium – 8% nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family. This stainless steel alloy may be considered for a wide variety of applications and exhibits good corrosion resistance, ease of fabrication, excellent formability, and high strength with low weight. 

Type 316, 316L

Alloys 316 (UNS S31600) and 316L (UNS S31603) are molybdenum-bearing austenitic stainless steels, which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Alloy 304. These alloys also offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures. In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steels.

Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications

Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications.

Austenitic stainless steels are iron-chromium-nickel alloys which are hardenable only by cold working. Nickel is the main element varied within the alloys of this class while carbon is kept to low levels. The nickel content may be varied from about 4% to 22% - higher values of nickel are added to increase to ductility of the metal. When chromium is increased to raise the corrosion resistance of the metal, nickel must also be increased to maintain the austenitic structure.


These alloys are slightly magnetic in the cold-worked condition, but are essentially non-magnetic in the annealed condition in which they are most often used. The austenitic types feature adaptability to cold forming, ease of welding, high-temperature service, and, in general, the highest corrosion resistance. Following are brief descriptions of some of our most commonly ordered stainless steels: 

Type 304L

Alloy 304L (UNS S30403) stainless steel plate is a variation of the 18% chromium – 8% nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family. This alloy may be considered for a wide variety of applications and exhibits good corrosion resistance, ease of fabrication, excellent formability, and high strength with low weight. 

Type 310, 310S

Alloy 310/310S (UNS S31000/S31008) austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304. 

Type 347 & 347H

Type 321

Alloy 347 (S34700) is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 347 is stabilized by the addition of columbium and tantalum.

Alloy 347 stainless steel is also advantageous for high temperature service because of its good mechanical properties. Alloy 347 stainless steel offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns. 

Alloy 321 (UNS S32100) is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 321 stainless steel is stabilized against chromium carbide formation by the addition of titanium.


Alloy 321 stainless steel is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.

Titanium Alloy

ASTM B265/ ASME SB-265

Titanium is most often alloyed with molybdenum, manganese, iron, and aluminum. By weight titanium is one of the strongest readily available metals, making it ideal for wide range of practical applications. It is 45% lighter than steel with comparable strength, and twice as strong as aluminum while being only 60% heavier. Titanium is suggested for use in desalinization plants because of its strong resistance to corrosion from sea water. Ti alloys consist of different grades with specific properties. Ti Grade 2 has moderate strength with excellent cold formability, weldability. This titanium also has excellent resistance to high oxidization. Titanium conductivity of heat and electricity is low. Titanium alloys can be employed at temperatures up to app. 400°C.


Duplex and Supper Duplex

UNS S31803, S32205, S32550, S32750, S32760

Duplex UNS S31803 F51, Super Duplex UNS S32750 F53, Super Duplex UNS S32760 Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%). The high corrosion resistance and excellent mechanical properties of duplex stainless steels can be attributed to their chemical composition and balanced (duplex) microstructure of approximately equal volume percentages of ferrite and austenite. Alloys 2304 and 2205 are the most common grades. They both exhibit outstanding resistance to chloride stress-corrosion cracking.


"Super" duplex grades have enhanced pitting and crevice corrosion resistance when compared with 300-series austenitic stainless steels or conventional duplex alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common "super" duplex grade.
