Nowadays, the use of stainless steel in the construction sector is
increasing day by day. And why not? Stainless steel is the most
economically viable and corrosion-resistant reinforcing steel
alternative in service environments. Once a structure is
constructed with stainless steel reinforcement, the need for
repairs throughout the life cycle of the project will reduce
significantly. That’s why even if at first, it may seem that
stainless steel rebars would be an expensive option, they prove to
be much more economical in the longer run. But what are stainless
steel rebars and how are they beneficial? Also known as stainless
steel reinforcement bars, stainless steel rebars are bars with low
carbon steel alloy content. They contain at least 12% of chromium
and 8 to 12% nickel. This makes them extremely durable and
resistant to corrosion.
Types Of Stainless Steels Rebars
There are 4 types of stainless steels:
- Martensitic Stainless Steel
- Ferritic Stainless Steel
- Austenitic Stainless Steel
- Duplex or Austenitic-Ferritic Stainless Steel
Out of these only Austenitic and Duplex Stainless Steels are used
to produce reinforcement bars.
Austenitic Stainless Steel Rebar
Austenitic steel is very high on nickel (around 7%). Due to this
reason, the alloy is extremely weldable and malleable and has
excellent corrosion resistance. It also has a high amount of
chromium and 2% to 3% of molybdenum addition. This further
strengthens its corrosion resistibility in harsh environments,
especially against chlorides. The Nitrogen content provides tensile
strength and a higher yield. Austenitic steel is mostly used for
industrial pipings and architectural projects as reinforcement bars
due to their high ductility, nonmagnetic nature, and large scale of
service temperature. It is classified into various grades in
different countries according to the proportion of elements present
in it.
Duplex Stainless Or Austenitic-Ferritic Stainless Steel Rebar
An amazing combination of ferritic and austenitic steels, duplex
stainless steels are stronger than both the types and is
extensively used in the underwater oil industry. This is due to its
high corrosion resistance capabilities that allow it to withstand
extremely corrosive saltwater for extended periods. Rebar is a
primary application for this steel. The blend of Austenitic and
Ferritic stainless steels has provided an exceptional element of
strength and corrosion resistance which has made it suitable for
various rebar applications like bridge decks, barrier and retaining
walls, anchoring systems and dowels, chemical plant infrastructure,
coastal piers and wharves, bridge parapets, sidewalks and bridge
pilings. Duplex Stainless Steel has lower nickel content as
compared to Austenitic steels which makes them less expensive. This
steel is also classified into different grades.
Properties Of Stainless Steel Rebars
Stainless steel rebars have been rigorously tested through various
parameters to see how they are superior to other rebars. They have
ranked considerably ahead as a substantial pack of alloys
differentiates them from other ineffective and fragile rebar
offerings.
1. High Strength Steel
Stainless steel contains 10% more chromium than other alloying
elements. Chromium is the key substance that increases its hardness
and tensile strength. It also contains nickel that provides similar
benefits but without compromising on ductility and toughness.
Duplex steel bars are stronger than austenitic steel bars.
2. Corrosion Resistance
Stainless steel rebars have a high concentration of chromium which
forms a layer of oxide that prevents corrosion. This property helps
it to withstand the destructive forces of chloride from road salts,
seawater, and even concrete itself. Austenitic stainless steel is
best in corrosion resistance since it contains at least 16%
chromium.
3. Ductility
The ductility of stainless steel rebar comes from its nickel
content. With excellent ductility and corrosion resistance, these
rebar products are perfect to use in earthquake zones, cold
applications, bridges, etc.
4. Magnetic Response
The high content of nickel in stainless steel bars eliminate their
magnetic response. Normal carbon steel has high magnetic
permeability and thus cannot be used in all applications. Here,
stainless steel rebars come to the rescue!
5. Fire Resistance
Stainless steel bars perform better at high temperatures as
compared to other carbon steel bars. They show better fire
resistance due to their high strength retention factor at elevated
temperatures (above 500°C).
6. Cryogenic Resistance
Stainless Steel Bars can handle a wider range of temperatures. The
tensile strength and toughness of austenitic steel remain intact
even in sub-zero temperatures which widen their scope of
application in various fields.
