Stainless steel reinforcing bars are low carbon steel alloy bars and contains minimum 12% of chromium and 8 to 12% of nickel in it. Stainless steel bars are highly corrosive resistant and they can be cast, pressed and machined.
Based on the microstructure, stainless steels can be divided into four types which are:

Austenitic Stainless steels are classified into different grades in different countries based on the proportions of main elements. Which are as follows
Table 1: Classification of Austenitic Steel according to International Standards
| Steel Type | Europe | USA | Britain | Sweden | |
| EN 10088-1 (DIN) | France | AISI | BS | SS | |
| Austenitic | 1.4301 | X5CrNi 18-10 | 304 | 314S11/314S15 | 2332 |
| 1.4401 | X5CrNiMo 17-12-2 | 316 | 316S33 | 2347 | |

| 1.4571 | X6CrNiMoTi 17-12-2 | 316Ti | - | 2350 | |
Austenitic-Ferritic steel has combined properties of austenitic and ferritic stainless steel hence it is also called as duplex stainless steel. It contains less amount of nickel than austenitic. It provides good strength as well as ductility.

It is very good resistant against corrosion. Duplex steels are widely used in paper, pulp, petrochemical industries etc. Duplex steel are also classified according proportion of main elements with different grade in different countries.

| Steel Type | Europe | USA | Britain | Sweden | |
| EN 10088-1 (DIN) | France | AISI | BS | SS | |
| Ferritic – Austenitic (lean duplex type | 1.4362 | X2CrNiMo 23-4 | 2304 | - | - |
| Ferritic – Austenitic (duplex type) | 1.4462 | X2CrNiMoN 22-5-3 | 2205 | 318 | 2377 |
Stainless steel bars majorly contain chromium and nickel as the second major compound. They also contain some other elements like molybdenum, nitrogen and very less amount of carbon. Composition of different grades of stainless steels is expressed in below table. The grades specified by AISI are taken into consideration.

| Type of Steel | Grade (AISI) | Chromium (%) | Nickel (%) | Molybdenum (%) | Nitrogen (%) | Carbon (%)(max) |
| Austenitic | 304 | 18 | 8 | 0.08 | ||
| 316 | 17 | 12 | 2.5 | 0.08 | ||
| 316LN | 17 | 12 | 2.5 | 0.13 | 0.03 | |
| Duplex | 2304 | 23 | 4 | 0.3 | 0.1 | 0.03 |
| 2205 | 22 | 5 | 3 | 0.14 | 0.03 |
Chromium, the major element of stainless steel gives protection against corrosion by forming an oxide film on the steel surface. This film is adherent, rough and invisible. Whenever the bar is attacked chemically this film prevents the bar by releasing small amounts of oxygen. Increase in chromium content will increase the chances of formation of oxide film under critical conditions. Nickel improves the properties like ductility and formability of stainless steel. Other elements like Molybdenum, nitrogen are also improves the corrosion resistance along with chromium.

The Properties of stainless Steel reinforcing Bars are
The main property of stainless steel is the corrosion resistance. As explained earlier the corrosion resistance is obtained by the oxide layer formed by chromium content of steel.
The tensile strength stainless steel bars is much more than mild steel bars. In stainless steels, duplex steel bars are stronger in tension than austenitic steel bars.
Ductility of stainless steel is due to nickel content. Higher the nickel content higher the ductility. Austenitic steel has more ductility than duplex steel.
At low temperatures, Austenitic Stainless steel bars have high tensile strength with excellent toughness. Other types like martensitic and ferritic are not suitable in cryogenic areas.
Steel generally has good fire resistance and when it comes to stainless steel, even at high temperatures it cannot lost its strength.
Except austenitic steel, all other types are able to attract to the magnet. Higher quantity of nickel eliminates the magnetic response of stainless steel.
