The difference between 304 and 304L
The steel 304L is 304 to reduce the carbon content to 0.03% or less
of the obtained steel, which is generally characteristic 304 is
almost the same, but this steel can be suppressed due to the
precipitation of chromium carbides caused sensitization between 500
~ 900oC of improving welding susceptibility to intergranular
corrosion caused by, and therefore suitable for large welded
structure to be welded directly to use timber and timber fittings.
Forming process of almost 304 species of the same, but the aging
cracking sensitivity is minimal.
In general corrosion, stress corrosion cracking, pitting resistance
characteristics and the same 304.
Benxi Iron and species characteristics is to improve the
intergranular corrosion susceptibility, will reduce the carbon
content to not produce thermal welding parts of the practical
problem. Between austenitic stainless steel to intergranular
corrosion due to the grain boundary chromium carbide (Cr23C6)
precipitation, 18 C solid solubility of Cr-8Ni steel last 0.02% at
800 ℃, C content than the solid solubility, the was heated to 600 ~
900 ℃, chromium carbides will precipitate in the grain boundaries
short time, reducing the amount of Cr within the austenite,
decreased corrosion resistance. Thus, by reducing the carbon
content in order to reduce the amount of precipitation of chromium
carbides, improved thermal sensitivity of purpose. Since the
phenomenon of intergranular corrosion in the heat affected zone of
welding is the most welding is heated to a temperature range of 600
~ 900 ℃ when it will occur, and the higher the C content of the
steel, the more significant, but less than 0.03% when the C content
will be sensitized to mitigate does not affect the degree.
