Austenitic stainless steels chemical composition

Alloy A286 is an austenitic, precipitation-hardenable stainless steel chemical composition will be found in Table 13.11. 

Susceptibility to intergranular corrosion also can occur in ferritic stainless steels (Ref 86-90). As with the austenitic stainless steels, the extent of the susceptibility is a function of the chemical composition and the thermal history of the steel. Also, the mechanism of intergranular attack is essentially the same for both classes of stainless steels, specifically, attack of lowered-chromium-content regions adjacent to precipitated chromium-rich carbides and nitrides. However, there are... 

The tested material is AISI 304 austenitic stainless steel whose chemical composition is shown in Table 1. The tensile test specimens are obtained, from sheets whose thickness is 1.5 mm, according to UNE-EN-ISO 6892-1 and have a gage length of 50 mm and a width of 12.5 mm.

Alloy G is a high-nickel austenitic stainless steel having the following chemical composition ... 

A metal resists corrosion by forming a passive film on the surface. This film is naturally formed when the metal is exposed to the air for a period of time. It can also be formed more quickly by chemical treatment. For example, nitric acid, if applied to austenitic stainless steel, will form this protective film. Such a film is actually a form of corrosion, but once formed it prevents further degradation of the metal, provided that the film remains intact. It does not provide an overall resistance to corrosion because it may be subject to chemical attack. The immunity of the film to attack is a fimction of the film composition, temperature, and the aggressiveness of the chemical. Examples of such films are the patina formed on copper, the rusting of iron, the tarnishing of silver, the fogging of nickel, and the high-temperature oxidation of metals. 

Because of their chemical composition and small intragranular precipitates, these materials can be used at temperatures higher than more conventional austenitic stainless steels. Interestingly, there are many similarities with conventional austenitic stainless steels such as ... 

In spite of their differences in chemical composition, precipitates, microstructures, etc., similarities in the creep behavior of austenitic stainless steels and tempered martensite-ferritic steels should be noticed such as ... 

One laboratory investigation has studied four high austenitic stainless steels and a duplex stainless steel. The low-alloy steel was tested since the corrosion inhibitors used were formulated for carbon and low-alloy steels. Chemical compositions (% by weight) and relevant mechanical properties in as-received conditions are respectively reported in Tables 8.6 and 8.7. 

First, a few studies on metal-filled composite bipolar plates are briefly described. At Los Alamos National Laboratory (LANL) composite bipolar plates filled with porous graphite and stainless steel and bonded with polycarbonate (Hermann, 2005) has been developed. Kuo (2006) investigated in composite bipolar plates based on austenitic chromium-nickel-steel (SS316L) incorporated in a matrix of PA 6. Their results showed that these bipolar plates are chemically stable. Furthermore, Bin et al. (2006) reported a metal-filled bipolar plate using polyvinylidene fluorid (PVDF) as the matrix and titanium silicon carbide (TijSiCj) as the conductive filler and obtained an electrical conductivity of 29 S cm" with 80 wt% filling content.
