Stainless steel is often divided into: martensitic steel, ferrite
steel, austenitic steel, austenitic - ferrite (duplex) stainless
steel and precipitation hardening stainless steel. In addition, can
be divided into: chromium stainless steel, chromium nickel
stainless steel and chromium manganese nitrogen stainless steel.
And special stainless steel for pressure vessels.
Austenitic stainless steel
It contains more than 18% chromium, 8% nickel and a small amount of
molybdenum, titanium, nitrogen and other elements. Good
comprehensive performance, can resist the corrosion of a variety of
media. Austenitic stainless steel commonly used grades are
1Cr18Ni9, 0Cr19Ni9, etc. 0 cr19ni9 steel Wc< 0.08%, marked
as "0" in the steel number. This type of steel contains large
amounts of Ni and Cr, making the steel austenitic at room
temperature. This kind of steel has good plasticity and toughness,
weldability and corrosion resistance and non-magnetic or weak
magnetic, the corrosion resistance in oxidizing and reducing medium
are good, used to make acid equipment, such as corrosion resistant
containers and equipment lining, pipelines, nitric acid resistant
equipment parts, etc., also can be used as the main body of watches
and clocks jewelry stainless steel material. Austenitic stainless
steel generally adopts solution treatment, that is, the steel is
heated to 1050 ~ 1150℃, and then water cooling or air cooling, in
order to obtain the single-phase austenite structure.
Austenitic ferrite duplex stainless steel
It has the advantages of austenitic and ferritic stainless steel,
and has superplasticity. Austenitic and ferrite structures each
account for about half of stainless steel. In the case of low
carbon content, the content of Chromium (Cr) is between 18% and
28%, and the content of nickel (Ni) is between 3% and 10%. Some
steels also contain Mo, Cu, Si, Nb, Ti, N and other alloying
elements. This kind of steel has the characteristics of austenitic
and ferritic stainless steel, compared with ferrite, higher
plasticity, toughness, no brittleness at room temperature,
intergranular corrosion resistance and welding performance are
significantly improved, but also maintain the 475℃ brittleness of
ferritic stainless steel and high thermal conductivity, with
superplastic characteristics. Compared with austenitic stainless
steel, it has higher strength and resistance to intergranular
corrosion and chloride stress corrosion. Duplex stainless steel has
excellent corrosion resistance and is also a nickel-saving
stainless steel.
