SEISMIC PROPERTIES
…REVAL = HIGH DUCTILITY AND TOUGHNESS SUPERIOR TO BLACK STEEL
REVAL 1.4307 (304L) and 1.4404 (316L), due to
their high content of nickel, a mineral of great toughness, are the
most suitable steels for reinforcing structures operating in seismic
areas. |

MAGNETIC
PROPERTIES
REVAL is a paramagnetic steel, due to its low
magnetic permeability.
It is used successfully in structures where disturbing strong magnetic
fields have to be avoided, such as in airports, military bases, broadcasting
stations, banks, meteorological stations, hospitals etc. |

STABILITY
AT LOW TEMPERATURES
REVAL’s austenitic structure remains stable
up to temperatures of -196°C suggesting its use in the coldest
environments .
Several countries have already made compulsory the use of stainless
steel in precast panels. |

BEHAVIOUR IN PRESENCE
OF FIRE
REVAL, being an austenitic steel shows an excellent
resistance to high temperature.
Its characteristics are:
• Low thermal conductivity
• A thermal linear expansion coefficient
which remains stable despite temperature variation, unlike black steel
• Permanent maintenance within safety
limits of all its properties at critical temperatures (with 55% of
residual 0,2% at 500°C). |

… JOINING STAINLESS STEEL TO BLACK
STEEL
REVAL can be easily and safetly joined, by
lapping or coupling, to black steel.
Extended laboratory research has proved that corrosion is contained
when stainless steel is electrically connected to black steel.
