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.
Heat resistant performance
Heat resistance refers to the high temperature stainless steel can
still maintain its excellent physical and mechanical properties.
Influence of carbon: Carbon is an element that strongly forms and
stabilizes austenite and enlarges the austenite zone in austenitic
stainless steel. The ability of carbon to form austenite is about
30 times that of nickel. Carbon is a interstitial element, and the
strength of austenitic stainless steel can be significantly
improved by solution strengthening. Carbon also improves the stress
and corrosion resistance of austenitic stainless steel in high
concentration chloride (e.g. 42%MgCl2 boiling solution).
But, in the austenitic stainless steel, carbon is often seen as the
harmful elements, this is mainly due to the corrosion of stainless
steel used in some conditions, such as welding or heating by 450 ~
850 ℃), carbon steel with chromium in forming high chromium Cr23C6
type carbon compounds which can lead to local chromium depletion,
make steel corrosion resistance especially resistant to
intergranular corrosion performance degradation. So. Since the 60 s
of the development of new cr-ni austenitic stainless steel is
mostly carbon content less than 0.03% or 0.02% of the ultra-low
carbon type, you can know as the carbon content is reduced, the
steel intergranular corrosion sensitivity is reduced, when carbon
content less than 0.02% is one of the most obvious effect, some
experiments also pointed out that the carbon will also increase the
chromium austenitic stainless steel corrosion tendency. Due to the
harmful effects of carbon, not only in the process of austenitic
stainless steel smelting should be as low as possible according to
the requirements of the control of carbon content, but also in the
subsequent hot and cold processing and heat treatment process to
prevent the surface of stainless steel carburization, to avoid
chromium carbide precipitation.
Corrosion resistance
When the amount of chromium atom in steel is not less than 12.5%,
the electrode potential of steel will change from negative
potential to positive electrode potential. Prevent electrochemical
corrosion.
