Product Details

UNS S31254 F44 Super Austenitic Stainless Steel is an  austenitic stainless steel. Due to its high density of molybdenum, it is highly  resistant to corrosion. This type of stainless steel is developed and developed  for use in environments such as seawater containing halides.

UNS S31254 F44 Super Austenitic Stainless Steel also has good anti-uniform corrosion  resistance. Especially in the acid containing halide, this steel is superior to  ordinary stainless steel. Its C contains <0.03%, so it is called pure  austenitic stainless steel.(<0.01% is also called super austenitic stainless  steel).Super stainless steel is a kind of special stainless steel.

First of all, it  is different from ordinary stainless steel in chemical composition. It is a  kind of high alloy stainless steel with high nickel, high chromium and high  molybdenum. One of more famous is containing 6% Mo F44 this kind of steel has  good resistance to local corrosion resistance, in sea water, air, there is gap,  low-speed scour condition, has the good point corrosion resistance (PI 40 or  higher) and good resistance to stress corrosion performance, is the substitute  material Ni base alloy and titanium alloy.

Secondly, in the  performance of high temperature or corrosion resistance, it has better  resistance to high temperature or corrosion resistance, which is not  replaceable by 304 stainless steel.

In addition,  from the classification of stainless steel, the metallographic structure of  special stainless steel is a stable austenite metallographic structure.
 Because of this  special stainless steel is a kind of high alloy material, so in the  manufacturing process is very complex, general people can only rely on the  traditional process to make this kind of special stainless steel, such as  perfusion, forging, rolling, and so on.

Product Description


F44 Stainless Steel High  Temperature Resistance:

1. A lot of  field experiments and extensive use experience shows that, even at a slightly  higher temperature in sea water also has the very high resistance crevice  corrosion performance, only a few kinds of stainless steel with the  performance.
 2. The corrosion  resistance of the acidic solution and the oxidized halide solution, such as the  bleach production of paper industry, is comparable to that of the nickel base  alloy with the strongest corrosion resistance.
 3. Due to the  high nitrogen content of F44, its mechanical strength is higher than that of  other types of austenitic stainless steel. In addition, it has high ductility  and impact strength and good weldability.
 4. The high  molybdenum content of F44 enables it to have a high oxidation rate during  annealing, and thus has a rougher surface than ordinary stainless steel after  pickling. But this has no adverse effect on the corrosion resistance of the  steel.
